Which of the following statements are True or False.
Matrix multiplication is commutative.
✓

Answer

False.Solution:
If AB is defined, it is not necessary that BA is defined.
Also if AB and BA are defined, it not necessary that they have same order. Further if AB and BA are defined and have same order, it is not necessary their corresponding elements are equal.
So, in general AB^BA
