Math.pow(base,exponent)

[edit] Parameters

base 

The base number.

exponents 

The exponent to which to raise base.

[edit] Description

Because pow is a static method of Math, you always use it as Math.pow(), rather than as a method of a Math object you created.

[edit] Examples

[edit] Example: Using Math.pow

function raisePower(x,y) {
   return Math.pow(x,y)
}

If x is 7 and y is 2, raisePower returns 49 (7 to the power of 2).
