// Java program to calculate the square root of a number using the Math.pow() function
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
    	Scanner in = new Scanner(System.in);

        System.out.println("Enter any number to find the square root::\n");

        double n = in.nextDouble();
        double r;
        // n = number
        // r = root

        /* Calculate square root of number */
        r = (double)Math.pow(n, 0.5);

        // Output
        System.out.println("\nSquare root of:: " + n + " = " + r + "\n");
