Question

Program Specifications

The built-in Java Math methods make some calculations much easier. Write a program called "DoTheMath" that accepts as input three floating-point numbers x, y, and z (define them as double) and outputs several calculations:

1. x to the power of y
2. x to the power of (y to the power of z)
3. The absolute value of x
4. The square root of (x*y to the power of z).

Sample Run:

Enter the values for x, y, z:
-3.7 -3 5
 <-- print a blank line before outputting calculations
x to the power y is -0.019742167295125655
x to the power y to the power z is -8.452419664263233E-139
The absolute value of x is 3.7
The square root of x*y to the power z is 410.49459863681534 <-- end with a println

honestly just kind of lost on how to do this.

Answer 1

import java.util.Scanner;

public class DoTheMath {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("Enter the values for x, y, z:");
        double x = in.nextDouble();
        double y = in.nextDouble();
        double z = in.nextDouble();
        //  <-- print a blank line before outputting calculations
        System.out.println();
        // x to the power y is -0.019742167295125655
        System.out.println("x to the power y is " + Math.pow(x, y));
        // x to the power y to the power z is -8.452419664263233E-139
        System.out.println("x to the power y to the power z is " + Math.pow(x, Math.pow(y, z)));
        // The absolute value of x is 3.7
        System.out.println("The absolute value of x is " + Math.abs(x));
        // The square root of x*y to the power z is 410.49459863681534 <-- end with a println
        System.out.println("The square root of x*y to the power z is " + Math.sqrt(Math.pow(x*y, z)));
    }
}
