For any two matrices A and B, A. AB = BA is always true B. AB =BA is

1.	For any two matrices A and B, A. AB = BA is always true B. AB =BA is never true C. sometimes AB = BA and sometimes AB ≠ BA D. whenever AB exists, then BA exists
Answer» If the two matrices A and B are of same order it is not necessary that in every situation AB = BA AB = BA = I only when A = B^-1 B = A^-1 Other time AB ≠ BA

Answer»

If the two matrices A and B are of same order it is not necessary that in every situation AB = BA

AB = BA = I only when A = B^-1

B = A^-1

Other time AB ≠ BA
