public class Cross{
 public static void main(String[] args){
  java.util.Scanner keyin=
   new java.util.Scanner(System.in);
  while(keyin.hasNext()){
   long input1 = keyin.nextLong();
   long input2 = keyin.nextLong();
   long sum=1;
   
   for(int a=1;a<=input2;a++){
     sum*=input1;
   }
   System.out.println(sum);
   
   
  }
 }
}

不知道是不是還要考慮負數次方??

有請神手XDDD

謝謝
