## POWER Function Syntax

## Arguments

number | The numeric value which you want to raise to a power. |

power | The numeric exponent value to raise power to. |

## Examples

### Calculating the *n*th power of a number

The function requires the **number** and the **power **arguments as input values. The **number **argument represents the base of the exponent operation. Thus, the **POWER** executes the x^{y} (x to the power of y) operation. For example, to calculate *4, raised to the power of 3*, use the following function:

### Calculating the *n*th root of a number

You can use the **POWER** function to calculate the *n*th root of a number. You can get the root of a number if you raise the number with a rational exponent.

As a result, using a rational exponent for the **power **argument gives the root of the specified number. For example, to calculate the cube root of *16*, you can use a formula like below.

## Tips

- Use rational exponents (1/y) for the
**power**argument to calculate*n*th root of a number using the**POWER**function. - Alternatively, you can use caret symbol (^) to find the result when a number is raised to the power. If the base is
*x*and the power is*y*, the formula would be
