Solution:

import java.io.*;

import java.util.*;

public class Main {

    public static void main(String[] args) throws Exception {

        // write your code here

        Scanner sc = new Scanner(System.in);

        int x = sc.nextInt();

        int n = sc.nextInt();

        System.out.println(power(x,n));

    }

    public static int power(int x, int n){

        if(n == 0) return 1;

        return x * power(x,n-1);

    }

}
