Step 1

The product of two matrices can be calculated if the number of columns of first matrix equals to number of rows of second matrix. Then the order of the resultant matrix is equal to number of rows of first matrix number of columns of second matrix. Generally the order of matrix is represented as

Step 2

The given matrices are

Hence, the value of matrix

Let B be a 4x4 matrix to which we apply the following operations:

1. double column 1,

2. halve row 3,

3. add row 3 to row 1,

4. interchange columns 1 and 4,

5. subtract row 2 from each of the other rows,

6. replace column 4 by column 3,

7. delete column 1 (column dimension is reduced by 1).

(a) Write the result as a product of eight matrices.

(b) Write it again as a product of ABC (same B) of three matrices.
