# Root

## Syntax

```swift
sqrt x
cbrt x
x root y
```

## Explanation

### `sqrt`/`cbrt`

`sqrt` and `cbrt`, find the square root and the cube root of the given operand respectively. They are aliases of `x root 2` and `x root 3`. There is minimal speed different, if any, and are simply exist for clearer code.

### `root`

`root` finds the $$n^{th}$$ root of `x` ($$\sqrt\[n]{x}$$), where $$n = y$$. It is equivilent to `x ** y ** -1`

## Examples

```swift
sqrt 16    // 4
cbrt 8     // 2
16 root 4  // 2
```
