# nth root of number

=number^(1/n)

To get the cube root of a number, you can use the caret(^) operator with 1/3 as the exponent in a simple formula. In the example shown, the formula in D5 is:

=B5^(1/C5)

### How this function works

By definition, the nth root of a number can be calculated by raising that number the power of 1/n. Exponents are entered using the caret (^) symbol, with a number on the left and power on the right. So, in this example we get the numbers from column B and powers from column C:

=B5^(1/C5)

If this idea is new to you, Khan Academy has good videos on the topic.

### With the POWER function

The POWER function is another way to perform exponentiation in Excel. Simply supply the number with 1/n for the power argument:

=POWER(number,1/n)

So for the example above, the formula in D5 would be:

=POWER(B5,1/C5)
