Java太威武了，我是来贴代码的import java.io.PrintWriter;
import java.math.BigDecimal;
import java.util.Scanner;
public class Main {
static Scanner cin = new Scanner(System.in);
static PrintWriter cout = new PrintWriter(System.out, true);
public static void main(String[] args)
{
BigDecimal a,c;
int b;
while (cin.hasNext())
{
a = cin.nextBigDecimal();
b = cin.nextInt();
c = a.pow(b);
String ans = c.toPlainString();
if (ans.contains(".") == false)
{
cout.println(ans);
}
else
{
int x = 0, y = ans.length() - 1;
while (ans.charAt(x) == '0') x++;
while (ans.charAt(y) == '0') y--;
if (ans.charAt(y) != '.') y++;
cout.println(ans.substring(x, y));
}
}
}
}
