On this page is a *root calculator*. Enter your index and radicand (base of the root) to complete an entire radical n√x and we will compute the *nth root*.

You can use this root calculator to compute square, cubic, and fourth root, but also try the dedicated calculators:

## What is the Root of a Number?

In mathematics, the root (general root) of a number is the number when multiplied by itself "n" times equals the *radicand*, or base of the radical.

In the above equations:

- n = the
*index*or number of times to multiply (exponent in the lower equation) - √ = the
*radical*sign (radix) - x = the
*radicand*, or the final value we'd get raising the root to the exponent

## Using the Root Calculator

To use the root calculator, merely enter the index (n) of the radical plus the radicand (number under the symbol). Then hit the **Compute Root** button and we'll compute the nth root for you in the **Root** box.
