Sqrt() Method:

The sqrt() method computes the square root of a number.

Let’s take an example,


class Main { 

public static void main(String[] args) {
          
int number = 25; 
          
double squareRoot; 

squareRoot = Math.sqrt(number ); 

System.out.println(squareRoot) ; 

} 
} 

// Output: 5.0

Pow() Method

The pow( ) method computes the power of the number


Class Main { 

Public static void main(String[] args { 

Double power = Math.pow(5.5, 2);

 System.out.println(power ); 

} } 
// Output: 30.25
