Question

Let A be a finite set of size n, then the number of element in the power set of A​

Answer 1

Step-by-step explanation:

Let A be a finite set of size n the number of power set of AxA is 2^n2.

The power set of a set A is the collection of all subsets of A. It contains every possible subset of A, including the empty set and the set A itself.

The power set of any set S is the set of all subsets of S, including the empty set and S itself, variously denoted as P(S).
