विकल्प
True
False
उत्तर
This statement is False.
Explanation:
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
