import java.util.*;

public class Calculator1 { public static void main(String args[]) { System.out.println("Enter numbers"); Scanner Reader = new Scanner(System.in); float num1 = Reader.nextFloat(); char Sign = Reader.next() .charAt(0); float num2 = Reader.nextFloat(); switch(Sign) { case '-' : { System.out.println(num1-num2); break; } case '+' : { System.out.println(num1+num2); break; } case '/' : { System.out.println(num1/num2); break; } case '*' : { System.out.println(num1*num2); break; } } } }

I was able to implement +,-,*,/ in my code, but I am having a hard time incorporating equations that find both square root and exponent to the code I already have. Is there a way to insert square root and exponent with the code that I already have? Thank you
