1
00:00:00,520 --> 00:00:02,810
Chúng ta có thể thấy khi số mũ của i tăng

2
00:00:02,810 --> 00:00:06,740
thì giá trị của chúng sẽ theo vòng từ

3
00:00:06,740 --> 00:00:11,260
1 đến i đến âm 1 đến âm i rồi lặp trở lại

4
00:00:11,260 --> 00:00:12,290
theo thứ tự giống vậy

5
00:00:12,290 --> 00:00:14,155
Liệu chúng ta có thể giải quyết

6
00:00:14,155 --> 00:00:15,780
các vấn đề phức tạp hơn những vòng

7
00:00:15,780 --> 00:00:17,110
lặp dễ nhìn thấy này không?

8
00:00:17,110 --> 00:00:18,526
Khá thú vị khi chúng ta có thể tìm ra được lũy thừa

9
00:00:18,526 --> 00:00:22,180
của i xoay vòng qua các giá trị này.

10
