Sets Exercise Ex. 1VSAQ
Solution 1
Let A be a set. Then collection or family of all subsets of A is called the power set of A and is denoted by P(A).
A set having n elements has 2n subsets. Therefore, if A is a finite set having n elements, then P(A) has 2n elements.
Solution 2
If A is the void set Φ, then P(A) has just one element Φ i.e. P(Φ) ={Φ}.
