Answer:
A x A={(a,a), (a,b), (b,a), (b,b)} which has 4 elements. Hence its power set P(A x A) has 2^4 = 16 elements. You can now write out all its subsets having 0, 1, 2, 3 and 4 elements. Do not forget the null set phi. For example the subsets will be: phi, {(a,a)}, {(a,b)}, {(b,a)}, {(b,b)}, {(a,a), (a,b)} etc etc. Then make the set with these 16 elements.
