Answer 1

$\textsf{\large{\underline{Solution}:}}$

The given problem is solved using language - Java.

import java.util.Scanner;

public class Brainly{

   public static void main(String s[]){

       Scanner sc=new Scanner(System.in);

       double n,sq,sqrt;

       System.out.print("Enter a number: ");

       n=sc.nextDouble();

       sc.close();

       sq=n*n;

       sqrt=Math.sqrt(n);

       System.out.println("The square of "+n+" is: "+sq);

       System.out.println("The square root of "+n+" is: "+sqrt);

   }

}

$\textsf{\large{\underline{Explanation}:}}$

• Take the number as input.
• To calculate square of the number, multiply the number by itself.
• To calculate the square root of the number, use Math.sqrt() function.

$\textsf{\large{\underline{Sample I/O}:}}$

Enter a number: 2.0

The square of 2.0 is: 4.0

The square root of 2.0 is: 1.4142135623730951
