Question

If n(p(a)is 30 ,what is n(a)

Answer 1

given n [p (a)]=256

if number of elements in set a

so n(a)=m

number of elements in power

set of a=n [p (a)] then

n [p (a)]= 2^m

here

2^m=n [p (a)]

=> therefore 2^m is given i.e 256

=>2^m= 2^8

=>m=8

{if a^p=a^q then p=q}

therefore

m=n (a)=8
