Ex2.1, 7 Let A = {1, 2}, B = {1, 2, 3, 4}, C = {5, 6} and D = {5, 6, 7, 8}. Verify that A (B C) = (A B) (A C) Since L.H.S = R.H.S Hence proved Ex2.1, 7 Let A = {1, 2}, B = {1, 2, 3, 4}, C = {5, 6} and D = {5, 6, 7, 8}. Verify that (ii) A C is a subset of B D A C = {1, 2} {5, 6} = {(1, 5), (1, 6), (2, 5), (2, 6)} Note all the elements of set A C are the elements of set B D. Therefore, A C is a subset of B D.
