Question

Write a program to calculate the value of the given expression: 
       1/a2 + 2/b2 + 3/c2 
Take the values of a, b and c as input from the console. Finally, display the result of the expression to its nearest whole number. ​

Answer 1

Answer:

import java.util.Scanner;

public class KboatExpression

{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

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

int a = in.nextInt();

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

int b = in.nextInt();

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

int c = in.nextInt();

double exp = (1 / Math.pow(a, 2)) + (2 / Math.pow(b, 2)) + (3 / Math.pow(c, 2));

long roundedExp = Math.round(exp);

System.out.println("Result rounded to whole number: " + roundedExp);

}
