If , then A2 is equal to

Q1 of 307 Page 6

If , then A² is equal to

Hence, the Option (B) is correct, as the main diagonal elements are 1 except other which are 0.

If is written as A = P + Q, where as A = P + Q, where P is symmetric and Q is skew-symmetric matrix, then write the matrix P.

Let A and B be matrices of orders 3 × 2 and 2 × 4 respectively. Write the order of matrix AB.

If , n ∈ N, the A⁴ⁿ equals

If A and B are two matrices such that AB = A and BA = B, then B² is equal to
