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

As no programming language is mentioned, I am writing this in Java.

import java.util.Scanner;

public class Brainly{

   public static void main(String s[]){

       int number, f,l;

       Scanner sc=new Scanner(System.in);

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

       number=sc.nextInt();

       sc.close();

       f=number/10;

       l=number%10;

       System.out.printf("Square of first digit = %d x %d = %d\n",f,f,f * f);

       System.out.printf("Square of last digit = %d x %d = %d",l,l,l * l);

   }

}
