Solution

A = 2x2

B = 2x2

C = 2x1

D = 1x2

E = 3x3

1.

AB = (2x{2)*(2}x2)

order will be digits remaining outside {} bracket.

AB = 2x2

2.

(A^2)C

Order does not change after square, So

A^2 = 2X2

(A^2)C = (2x{2)*(2}x1) = 2x1

3.

B^2 + 3CD

Adding is only when order is same in all matrices

order of B^2 = order of 3 CD = order of (B^2 + 3CD)

we know that

order of B^2 = order of B = 2x2

order of CD = (2x{1)*(1}x2) = 2x2

order of (B^2 + 3CD) = 2x2

4.

DC + BA

order of DC = order of BA = order of (DC + BA)

Order of BA = (2x{2)*(2}x2) = 2x2

order of DC = (1x{2)*(2}x1) = 1x1

order of (DC + BA) = DNE

5.

C - 2D

order of C = order of 2D = order of (C - 2D)

order of C = 2x1

order of 2D = 1x2

order of (C - 2D) = DNE
