00:00:00.000 --> 00:00:03.971
Here is the problem: A to the power n (power): A equals [[1, 2], [3, 4]].

2
00:00:04.421 --> 00:00:06.917
Compute A to the power n (power) exactly.

3
00:00:07.717 --> 00:00:09.075
Read matrix A.

4
00:00:09.525 --> 00:00:11.476
Multiply again: power 2.

5
00:00:11.926 --> 00:00:12.576
Result.

6
00:00:13.376 --> 00:00:17.916
So the answer is A to the power n (power) equals [[7, 10], [15, 22]].

7
00:00:18.366 --> 00:00:22.070
A squared is computed by repeated exact multiplication.

8
00:00:22.870 --> 00:00:26.225
All arithmetic is exact (fractions, no rounding).
