# Function pow

Calculates the power of x to y, `x ^ y`.

Matrix exponentiation is supported for square matrices `x` and integers `y`:
when `y` is nonnegative, `x` may be any square matrix; and when `y` is
negative, `x` must be invertible, and then this function returns
inv(x)^(-y).

For cubic roots of negative numbers, the function returns the principal
root by default. In order to let the function return the real root,
math.js can be configured with `math.config({predictable: true})`.
To retrieve all cubic roots of a value, use `math.cbrt(x, true)`.


## Syntax

```js
math.pow(x, y)
```

### Parameters

`x` | number &#124; BigNumber &#124; Complex &#124; Unit &#124; Array &#124; Matrix | The base
`y` | number &#124; BigNumber &#124; Complex | The exponent

### Returns

Type | Description
---- | -----------
number &#124; BigNumber &#124; Complex &#124; Array &#124; Matrix | The value of `x` to the power `y`

## Examples

```js
math.pow(2, 3)               // returns number 8

const a = math.complex(2, 3)
math.pow(a, 2)                // returns Complex -5 + 12i

const b = [[1, 2], [4, 3]]
math.pow(b, 2)               // returns Array [[9, 8], [16, 17]]

const c = [[1, 2], [4, 3]]
math.pow(c, -1)               // returns Array [[-0.6, 0.4], [0.8, -0.2]]
```
