# JavaScript Math cbrt() Method

Below is the example of the Math cbrt() Method.

• Example:

 `  `

• Output:
```cbrt of 16: 4
cbrt of 27: 3
cbrt of 0: 0
cbrt of -1: -1
cbrt of -27: -3
cbrt of Infinity : Infinity```

The Math.cbrt() method is used to find cube root of a number.
Syntax:

`Math.cbrt(x)`

Parameters: This method accepts a single parameter as mentioned above and described below:

• x: This parameter is a simply a number whose cube root need to be find.

Returns: It returns the cube root of the given number.

Below example illustrate the cbrt() method in JavaScript:
Example: Here cube root of 8 is calculated to 2 because when any 3 times repeated any number is present inside of the cube root then only one number is taken out as the value of the cube root.
∛8
= ∛2*2*2
= 2

```Input: Math.cbrt(8)
Output : 2
```

More codes for the above method are as follows:

Program 1: Errors and Exceptions, it is an error case because cube root of complex number can not be found that is why its parameter gives error.

 `  `

Output:

`Error: Invalid or unexpected token`

Program 2: Cube root of string can not be found that is why string parameter of the function gives NaN i.e, not a number. An only integer value can be used as the parameter for the function.

 `  `

Output:

`cbrt of a string: NaN`

Program 3: Whenever we need to get cube root of any number that time we take the help of the Math.cbrt() function in JavaScript.

 `  `

Output:

```Output : 5
Output : 2.8438669798515654```
