Prove that A is in the subset B if P(A) is in the subset P(B)

natima [27]

Show that if p(a) ⊂ p(b) then a ⊂ b.

I will assume p() means power set. 

proof: let x∈a, then {x} ∈ p(a) and so by hypothesis {x} ∈ p(b). However {x} could not be in p(b) unless x∈b. This shows that each element of a is an element of b and hence a ⊂ b.
