Hey guys i have, A = {1,2,3,4} and B = {2,3,5}, list the following elements:

1. Powerset(A) \ Powerset(B)

Does that mean, find Powerset(A) first then Powerset(B) then if Powerset(A) has subsets the same as Powerser(B), then remove those sets. Then the remaining subsets of Powerset(A) will = Powerset(A) \ Powerset(B) ?

thanks for the help!
