# JavaScript Math cbrt() Method

• Last Updated : 02 Jan, 2023

The Math.cbrt() method is used to find the 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 simply a number whose cube root needs to be found.

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

Example: Below is an example of the Math.cbrt() Method.

## javascript



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

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. âˆ›8 = âˆ›2*2*2 = 2

## Javascript



Output:

cbrt of 8 : 2

Example: Errors and Exceptions, it is an error case because the cube root of a complex number can not be found which is why its parameter gives error.

## javascript



Output:

Error: Invalid or unexpected token

Example: The cube root of the string can not be found which is why the string parameter of the function gives NaN i.e, not a number. Only integer value can be used as the parameter for the function.

## javascript



Output:

cbrt of a string: NaN

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

## javascript



Output:

Output : 5
Output : 2.8438669798515654
