The Math.pow() method is used to power a number i.e., the value of the number raised to some exponent. Since Math.pow() is a static method of Math and therefore it is always used as Math.pow() and not as a method of an object created in Math class. 

Syntax:

Math.pow(base, exponent)

Parameters:

  • base: It is the base number that is to be raised.
  • exponent: It is the value used to raise the base.

Return Value: The Math.pow() method returns a number representing the given base raised to the power of the given exponent

Example: 

javascript




<script type="text/javascript">
    console.log(Math.pow(3, 4));
</script>


Output:

81

More codes for the above method are as follows: 

Program 1: When both base and exponent are passed as positive numbers in parameters: 

javascript




<script type="text/javascript">
    console.log(Math.pow(9, 3));
</script>


Output:

729

Program 2: When the base value is negative and the exponent is positive: 

javascript




<script type="text/javascript">
    console.log(Math.pow(-9, 3));
</script>


Output:

-729

Program 3: When the base value is positive and the exponent is negative:

javascript




<script type="text/javascript">
    console.log(Math.pow(9, -3));
</script>


Output:

0.0013717421124828533

Program 4: When the base value is negative and the exponent has decimal point: It returns NaN.
