If A = [[1, 0], [0, 1]] and B = [[0, 1], [1, 0]], then AB is equal to: A. [[0, 1], [1, 0]] B. [[1, 0], [0, 1]] C. [[0, 0], [0, 0]] D. [[1, 1], [1, 1]] Answer: A) [[0, 1], [1, 0]] Explanation: AB = [[1×0+0×1, 1×1+0×0], [0×0+1×1, 0×1+1×0]] = [[0, 1], [1, 0]] = B. Since A is the identity matrix, AB = B.

imo class 12 matrices

If A = [[1, 0], [0, 1]] and B = [[0, 1], [1, 0]], then AB is equal to:

Answer: A) [[0, 1], [1, 0]]

Explanation: AB = [[1×0+0×1, 1×1+0×0], [0×0+1×1, 0×1+1×0]] = [[0, 1], [1, 0]] = B. Since A is the identity matrix, AB = B.
