import java.math.BigDecimal;
import java.util.Scanner;

public class Main {
	double r=0;
	int n=0;

	public Main() {
		Scanner cin = new Scanner(System.in);
			while(cin.hasNext()){
			r=cin.nextDouble();
			n=cin.nextInt();
			BigDecimal bigr=BigDecimal.valueOf(r);
			bigr=bigr.pow(n);
			String output=bigr.toPlainString();
			if(output.startsWith("0"))
				output=output.substring(1);
			System.out.println(output);
		}
	}

	public static void main(String[] args) {
		Main m = new Main();
	}
