Proving Sets?

Question

If A and B were sets how would I prove that P(A) is an element of P(B), and also, how A is an element of B? Thanks!!!

Answer 1

it is not necessary
define the sets.
p(A) is not necessarily the subset of p(B) and vice versa

Answer 2

I'm not exactly sure what you are asking...I know what P(A) and P(B) are, but without other information I don't think P(A) is necessarily an element of P(B)
