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}.
