**Calculate any exponent** con nuestra calculadora online. Simplemente tienes que introducir el valor de la base y el del exponente para saber el valor que estás buscando.

In case you don't remember, let's refresh what is the base and what is the exponent. For example, in 2^{3} we have to:

- The base is number 2
- The exponent is the number 3, that is, the number of times by which we multiply the base.

If you want to calculate the exponent of an exponentiation, you can do it in the link that we have just left.

## What is an exponent?

As we have already mentioned, an exponentiation is composed of two elements: base and exponent. The exponent indicates the **number of times that the base factor is repeated**, es decir, si tenemos 2^{6} means that we have to multiply the number two by itself a total of six times (2 · 2 · 2 · 2 · 2 · 2 · 2 · 2 = 64).

In this case, calculating the value of the exponentiation is simple but if we work with larger numbers, the calculation becomes more complicated and it is much more convenient to use **exponent calculators** like ours.

If what you need is to remove** the value of the exponent**, entonces debes usar la logarithm operation with which, through the value of the exponential and the base, you will find the number of times by which the number has been multiplied. In the link we have left you will find all the details to find the value of the exponent in an exponentiation.

## Powers of negative numbers

If we calculate the power of a negative number, the final result can have a positive or negative sign depending on the value of the exponent. Below we explain the possible cases:

**Even exponent**: In this case, we will always obtain a positive result since there is no negative number that, when multiplied by itself an even number of times, gives us a negative result.**Odd exponent**: in this case the negative symbol is respected.

## Properties of powers

Below you will find details of the **properties of powers** so that you can take them into account when solving your exercises.

### Powers of zero

Any **number raised to zero** is equal to 1. Mathematically, this is expressed in this form:

a^{0} = 1

For example:

6^{0} = 1

The same is true for any other value.

### Power of one

In this case, any **number raised to one** is equal to the number itself. That is to say:

a^{1} = a

Like **worked example** of this property, we have this one:

7^{1} = 7

### Power of negative one

If the exponent of the power is a nonzero, negative integer, the power can be expressed as a fraction.

a^{-n} = 1/a^{n}

For example, let's convert the following to a fraction **power with negative exponent**:

2^{-2} = 1/2^{2} = 1/4

### Multiplying powers with the same base

If you are going to **multiply several powers** that share the same base, the result is a power with that base but whose exponent is the sum of the exponents.

a^{m} · a^{n} = a^{m+n}

Solved example of **multiplication of powers with the same base**:

3^{2} · 3^{4} = 3^{2+4} = 3^{6}

### Product of powers with the same exponent

In the case of having to multiply two powers with the same exponent but different bases, what we have to do is to keep the exponent and multiply the bases:

a^{n }· b ^{n }= (a · b)^{n}

For example:

2^{2} · 3^{2} = (2 · 3)^{2} = 6^{2} = 36

### Dividir potencias con la misma base

If we are going to **divide several powers with the same base**In this case the exponents are subtracted as you can see below:

a^{m} : a^{n} = a^{m-n}

This is the corresponding solved exercise of division of powers:

4^{7} : 4^{3} = 4^{7-3} = 4^{4}

### Dividing powers with the same exponent

For this case of **power division**we keep the exponent but divide the bases by each other

a^{n }: b ^{n }= (a : b)^{n}

Example:

8^{2} : 4^{2} = (8 : 4)^{2} = 2^{2} = 4

### Power of power

In the case of having a **power of power**, what we have to do is to multiply the exponents as you can see in the following generic example:

(a^{m})^{n}=a^{m - n}

If we apply it to a practical exercise, we will see it better:

(2^{2})^{3} = 2^{6} = 64

## How to create your own exponent calculator in Excel

If you want to **calculating powers in Excel**, también puedes hacerlo aplicando la siguiente función en una celda:

=POWER(A1;B2)

O si lo prefieres, también puedes utilizar esta fórmula para **writing powers in Excel** que nos dará exactamente el mismo resultado:

=A1^B2

In both cases, you should keep in mind that:

- A1 are the coordinates of the cell in which the base of the power is located.
- B2 are the coordinates of the cell in which you have written the exponent.

You will have to adapt the value of those coordinates to your spreadsheet to create a **exponent calculator** automated using Microsoft software.

If you are not sure what the base or exponent of a power is, read the first part of this post where we explain what each one is.

## How to calculate powers in Casio calculator

If you have a Casio calculator, you can **calculate powers** very easily. The most common methods are explained below.

### Exponent 2 or raising a number to the square

To use the Casio calculator to square a number, simply locate the key with the x^{2} symbol engraved on its surface.

When you have located it, simply type the number to be squared, press that key (x^{2}) y, a continuación, presionas el igual (=) para obtener el resultado.

### Exponent 3 or raising a number to the cube

En este caso, veremos que la función secundaria de la tecla x^{2} is x^{3}raising a number to the cube.

The process to follow is as follows:

- Type the number you want to cube
- Press the Shift key and then the key on which the secondary function is located.

### Negative exponent or any other number

For some time now, Casio calculators have allowed us to raise any number to any exponent, even if it is a negative number. To achieve this, the first thing to do is to locate the key that has an **x raised to a blank square** o, en algunos casos, también está representada como x^{y}.

In the video we have just shown you, we explain how you can **calculate powers with any exponent**, including negative numbers, using a CASIO calculator.

## How to use the power calculator

If you're not quite sure how to use our power calculator, we've recorded a **video in which we propose several practical examples** so that you can solve any doubt about how it works. We hope it will be helpful, but if you still have any doubts, leave us a comment and we will help you as much as we can :)

## Addition and subtraction of exponents

**How to add and subtract exponents** is one of the most frequent doubts when facing an operation.

In both the addition and subtraction of powers it is essential that **solve them individually and add up the value of each one.** to obtain the result of the operation.

**In no case may you add the exponents or the bases.** because the result you will get will be wrong. You can check this as we have indicated before, that is, solving each exponential individually and checking that you do not get the result.

Let's see it with an example in which we want to add 3^{2} + 3^{2}

If we do it step by step we have:

3

^{2}+ 3^{2}= 9 + 9 = 18

If we do it in the wrong way** adding the exponents** let's see what happens:

3

^{2}+ 3^{2}= 3^{4}= 81

As can be seen, **the result is NOT the same and is correct only in the first case**.

If you need** find out the value of the exponent**, then you need to perform the logarithm operation with which, through the value of the exponential and the base, you will find the number of times by which the number has been multiplied.

great

very useful

Very useful, thank you

Best utility I've ever seen, you got me out of a bind on my math homework.

xD is a kind of calculator for people with little desire to do things.

Or for people who are addicted to pokemon, but have to do some work and are too lazy to calculate, I include myself xdd

This thing is very useful to get my accounts thank you.

this is the best page with respect to the others, because it helps me in my homework, I only do it in calculator hehe I love it thank you.

If you have any questions, let us know and we will help you.

Greetings!

thank you very, very much. it has been very helpful.

Thanks for your comment Oscar, that gives us strength to continue making more calculators. We hope to see you here more often and if you have any doubt about how to calculate powers, just let us know :)

it's the best site. it gives me the right answers, not like the others where I type something and I get something completely different. thank you very much for helping me with my doubts.

That's what Karen is all about, helping you to calculate the powers :)
