The **Math.pow()** is an built-in method in Java `Math`

class and is used to calculate the power of a given number.

The **power** of a number refers to how many times to multiply the number with itself.

The signature of the `pow()`

method is as follows:

- The method takes the base and exponent parameters of type
`double`

. - The method calculates multiplication of the base with itself exponent times and returns the result of type
`double`

.

See the following code snippet for example:

double pow(double base, double exponent)

The `pow()`

method is a part of `java.lang.Math`

class, you need to import this class in your code to use the function.

Using the `pow()`

method let’s calculate the following:

- $5^4$
- $1.5^3$
- $50^5$

import java.lang.Math; class CalculatePower { public static void main( String args[] ) { //Calculating 5^4 and casting the returned double result to int int ans1 = (int) Math.pow(5,4); System.out.println("5^4 is "+ans1); //Calculating 1.5^3 and storing the returned double result to ans2 double ans2 = Math.pow(1.5,3); System.out.println("1.5^3 is "+ans2); //Calculating 100^5 and casting the returned double result to int double ans3 = Math.pow(50,5); System.out.println("50^5 is "+ans3); } }
