Answer 1

Heya,Pikachu♥️✌️

✏️If A is a set.

Then, n(A) is called cardinal number of the set A = number of elements in set A.

P(A) is called power set of A. Power set =P(A)= set of all subsets of set A

We know that if number of elements in set A is n

n(A)=N

Number of subsets of power set =2n

Given,

n[P(A)]=16

2n=16

2n=24

Therefore, n=4
