72. If A be a finite set of size n, then number of elements in the power set of A x A is
- Option : B
- Explanation : If A is a finite set with |A| = n elements, then the number of powersets of A is 2n and here we have 2 sets of A i.e. A*A i.e. A2 so total elements = n2 So powersets pf A*A = 2n^2.So answer is (B)
