用for while while do循环，if语句作答

求出按照1＋3×3×3＋5×5×5×5＋7×7×7×7×7×7×7＋…这个规律的前8项之和

是5个5相乘吧，少了个5

public class Main {
    public static void main(String[] args) {
        long sum = 0;
        for(int i=1;i<=8;i++) {
            long t = 2*i-1;
            for(int j=1;j<=2*i-1;j++)
                t *= t;
            sum += t;
        }
        System.out.println(sum);
    }
}
