Question

if n[p(A)] = 64 THEN FIND N(A)
​

Answer 1

Step-by-step explanation:

n [P(A)] = 64

We know,

n [P(A)] = All the subsets of (A) = 64

So,

Total subsets of (A) =  $2^{m}$                      [ m = elements of (A) ]

                                =>  $2^{m}$  = 64

                                =>  $2^{m}$  = $2^{ 6}$

∴        m = 6

So, no. of elements of (A) = n (A) = 6          ( Ans )
