Question

Write a program to calculate the value of the given expression: 

`1/a^2 + 2/b^2 + 3/c^2`

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

import java.util.*;
public class Q1
{public static void main(String args[])
{Scanner in = new Scanner(System.in)
int a, b, c;
long s;
double x;

System.out.println("Enter the three numbers");
a = in.nextlnt();
b = in.nextlnt(); 
c = in.nextlnt();

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

s = Math.round(x);
System.out.println(s);
