Java Program to Compute (ab)x where Value of a, b and x are Given

In the previous article we have discussed Java Program to Compute a4+a2+1 where Value of a and b are Given

In this program we are going to see how to compute (ab)^x where value of a, b and x are given.

Java Program to Compute (ab)^x where Value of a, b, and x are Given

The formula of (ab)^x is given below.

(ab)^x = a^x * b^x

Now we will convert this into a valid Java expression.

Let x

= (ab)^x

= a^x * b^x

Example:

Suppose a=2, m=2, and n=2

Then,
(ab)^x 
= a^x * b^x
=2^2 * 2^2
=4 * 4
=16

Now let’s see different ways to compute (ab)^x.

By Using pow() Function and Static Input Value
By Using pow() Function and User Input Value
By Using User Defined Method

Method-1: Java Program to Compute (ab)x where Value of a, b and x are Given By Using pow() Function and Static Input Value

Approach:

Declare and initialize three integer variables say a, b and x.
By using the formula compute (ab)^x .
Print the result.

Program:

import java.lang.Math;
public class Main
{
    public static void main(String[] args)
    {
        //declare the first integer variable with a integer value
        int a= 4;
        System.out.println("a= " +a);
        //declare the second integer variable with a integer value
        int b= 4;
        System.out.println("b= "+b);
        //declare the third integer variable with a integer value
        int x= 2;
        System.out.println("x= "+x);
        //declare another integer variable and assigned the formulated value to it.
        int res= (int)(Math.pow(a,x) * Math.pow(b,x));
        System.out.println("(ab)^x  = "+res);
    }
}

Output:

a= 4
b= 4
x= 2
(ab)^x  = 256

Method-2: Java Program to Compute (ab)x where Value of a, b and x are Given By Using pow() Function and User Input Value

Approach:

Declare three integer variables say a, b and x.
Prompt the user to enter the values to the corresponding variables by using Scanner class.
Then By using the formula compute (ab)^x .
Print the result.

Program:

import java.lang.Math;
import java.util.Scanner;

class Main
{
    public static void main(String[] args)
    {
        //create object of scanner class.
        Scanner sc=new Scanner(System.in);
        System.out.print("a= ");
        //Take the first input from the user.
        int a= sc.nextInt();
        System.out.print("b= ");
        //Take the second input from the user.
        int b= sc.nextInt();
        System.out.print("x= ");
        //Take the third input from the user.
        int x= sc.nextInt();
        //declare another integer variable and assigned the formulated value to it.
        //declare another integer variable and assigned the formulated value to it.
        int res= (int)(Math.pow(a,x) * Math.pow(b,x));
        System.out.println("(ab)^x  = "+res);
    }
}

Output:

a= 2
b= 4
x= 5
(ab)^x  = 32768

Method-3: Java Program to Compute (ab)x where Value of a, b and x are Given By Using User Defined Method

Approach:

Declare three integer variables say a, b and x.
Prompt the user to enter the values to the corresponding variables by using Scanner class.
Then call a user defined method say computeValue() and pass a, b, and x as parameter.
Then inside method by using the formula compute (ab)^x .
Print the result.

Program:

import java.util.Scanner;

class Main
{
    public static void main(String[] args)
    {
        //create object of scanner class.
        Scanner sc=new Scanner(System.in);
        System.out.print("a= ");
        //Take the first input from the user.
        int a= sc.nextInt();
        System.out.print("b= ");
        //Take the second input from the user.
        int b= sc.nextInt();
        System.out.print("x= ");
        //Take the third input from the user.
        int x= sc.nextInt();
        //call the funtion
        computeValue(a,b,x);
    }
    
    //computeValue() method
    public static void computeValue(int a, int b,int x){
        //declare another integer variable and assigned the formulated value to it.
        int res= (int)(Math.pow(a,x) * Math.pow(b,x));
        System.out.println("(ab)^x  = "+res);
    }

}

Output:

a= 4
b= 3
x= 4
(ab)^x  = 20736
