Java Program: Print Powers of a Number

Write a program that accepts a number x and then prints:

x0, x1, x2, x3, x4, x5

Java 
import java.util.Scanner;


 


public class PowersOfX {


    public static void main(String[] args) {


        Scanner sc = new Scanner(System.in);


 


        // Input value


        System.out.print("Enter the value of x: ");


        int x = sc.nextInt();


 


        // Print powers from x^0 to x^5


        System.out.println("Powers of x are:");


        for (int i = 0; i <= 5; i++) {


            System.out.println("x^" + i + " = " + Math.pow(x, i));


        }


 


        sc.close();


    }


}

Output


Sample Input 
Enter the value of x: 2

Sample Output 
Powers of x are:
x^0 = 1.0
x^1 = 2.0
x^2 = 4.0
x^3 = 8.0
x^4 = 16.0
x^5 = 32.0

Explanation

  • Math.pow(x, i) computes x raised to the power i.
  • A for loop runs from 0 to 5 to generate all required powers.
  • x⁰ is always 1 for any non-zero x.
