When we want to get a root of a number, it is as same as raising that number to the power of 1/root.

**Square Root:**

The square root of x is x^(1/2)

The square root of A1 is: =A1^(1/2)

Built-in worksheet function

SQRT: =SQRT(A1)

To find the Square root

Open an Excel file

Let’s find the square root of a number

Here the number is 169

The formula is

Square root =POWER(E3,1/2)

When we use the formula of POWER, we get 13 as the SQUARE ROOT of 169

**Cube Root:**

The cube root of x is x^(1/3). The cube root of A1 is: =A1^(1/3)

You can also use the built-in worksheet function POWER: =POWER(A1;1/3)

To find the Cube root

Cube root =POWER(E3,1/3)

Let’s check this formula

Cube root of 125

The formula is

Cuberoot =POWER(E3,1/3)

When we use the formula of POWER, we get 5 as the CUBE ROOT of 225

**Nth Root**:

Formula for nth root is POWER(NUMBER,1/n)
