Although we usually work with square roots or even we calculate cube rootsIf we need to use a **know the n-th root of a number**. This means that by multiplying the root value a total of n times, we obtain the initial number on which we calculate the root (radicand).

You can then use our **online n-th roots calculator** for you to define the value of the radical index:

## How the root calculator works

When you want to **calculate a root**In order to make it easier for you to understand the different parts of which it is composed, it is important that you are very clear about the parts of which it is composed. In the previous chart you can see what they are, but we are going to focus on the most important ones:

**Index**will indicate the type of root you want to calculate. If it is square it will be a 2, if it is cubic it will be a 3, if it is a quarter it will be a 4 and so on. In the end it is called nth root because n can be any positive number.**Radicand:**is the number for which you want to calculate the root.

On this basis, in our** online root calculator** just type the number and the value of the index (n). When you have done this, press the calculate button and you will get the result immediately.

## Solve n-th root in Excel

**Excel does not have a specific function to calculate nth roots.**s so we will use a "trick" that consists of expressing a root as a power that we can do from the Microsoft spreadsheet program.

If you do not know how to** expressing a root as a power**Simply follow the example shown in the following image:

For example, if you want to calculate the fifth root of 3, then it would be expressed as 3^{1/5}

Now that we know how to express roots as a power, we simply go to Excel and type the following formula:

=number^exponent

To calculate the fifth root of 245 we would write the function as follows:

=243^(1/5)

It's easy, isn't it?

## Nth root on the scientific calculator

If you have a scientific calculator at hand, you can also calculate nth roots with ease. Simply locate the button we have indicated with the arrow and press the following key combination:

index → SHIFT → x

^{■ }→ number → =

Obviously, where we have written "index" and "number" you will have to replace them with the corresponding numerical values.

As you have seen, there are multiple ways to **solve roots** of this type in which the value of the index does not have to be 2 or 3 as we are used to... If you have any doubts, leave us a comment and we will try to solve them as soon as possible.

It was very helpful.

Thank you.

It even works with the enlarged calculator of the cell phone.

I'm glad you found our information about the nth root useful.

If you need anything else or have any questions, please let us know.

Greetings!

thank you, very good contribution
