# Math.cbrt()

The **`Math.cbrt()`** function returns the cube root of a number.

## Syntax

```js
Math.cbrt(x)
```

### Parameters

- `x`
  - : A number.

### Return value

The cube root of `x`.

## Description

Because `cbrt()` is a static method of `Math`, you always use it as `Math.cbrt()`, rather than as a method of a `Math` object you created (`Math` is not a constructor).
