Find the product AB. where

Step 1:

In this problem we have to find AB matrix for these matrices.

Matrix Multiplication : if A be any matrix of order and B is an matrix , then their matrix product AB is an matrix , in which the m entries of row of A are multiplied with the m entries down a columns of B after then we summed to produce an entry of AB.

Step 2:

a: we given the matrices A and B,

where

Then

Hence we get
