Computer Applications
Write a program to input a number. Calculate its square root and cube root. Finally, display the result by rounding it off.
Sample Input: 5
Square root of 5= 2.2360679
Rounded form= 2
Cube root of 5 = 1.7099759
Rounded form= 2

public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter the number: ");
int num = in.nextInt();
double sqrtValue = Math.sqrt(num);
double cbrtValue = Math.cbrt(num);
long roundSqrt = Math.round(sqrtValue);
long roundCbrt = Math.round(cbrtValue);
System.out.println("Square root of " + num + " = " + sqrtValue);
System.out.println("Rounded form = " + roundSqrt);
System.out.println("Cube root of " + num + " = " + cbrtValue);
System.out.println("Rounded form = " + roundCbrt);
