Question

If n (P(A))=16 then n(A)=​

Answer 1

Answer:

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 =2^n

Given,

n[P(A)]=16

2^ n =16

2 ^n =2 ^4

Therefore, n=4
