If and, then verify that

(A + B). = A’ + B’

(A+B)’ = A’+B’

Explanation: Calculate matrix A by taking transpose of A’ and also find the transpose of matrix B and the solve L.H.S and R.H.S separately and then compare the result.

So, A = transpose of A’

B’ = transpose of B

From equation 1 & 2 we verify that

(A+B)’ = A’+B’. Hence verified.
