## Explanation

By definition, the nth root of a number can be calculated by raising that number to the power of 1/n. Exponents are entered using the exponentiation operator (^), 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)
```

### With the POWER function

The POWER function is another way to perform exponentiation in Excel. To get the nth root of a number with POWER, use the number with 1/n for the *power* argument:

```
=POWER(number,1/n)
```

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

```
=POWER(B5,1/C5)
```
