Answer 1

Answer:

The answer is 3.

Step-by-step explanation:

Answer :

9

Solution :

⎡⎣⎢100210a41⎤⎦⎥⎡⎣⎢100210a41⎤⎦⎥[12a014001][12a014001]

⎡⎣⎢1004102a+881⎤⎦⎥⎡⎣⎢100210a41⎤⎦⎥=⎡⎣⎢1006103a+24121⎤⎦⎥[142a+8018001][12a014001]=[163a+240112001]

∵⎡⎣⎢100210a41⎤⎦⎥=⎡⎣⎢1002n10na+8∑n−1k=0k4n1⎤⎦⎥∵[12a014001]=[12nna+8∑k=0n-1k014n001]

Hence n=9n=9
