Question: Prove that A (B C) = (A B) (A C). To prove S = T, where S and T are sets, prove that each set

Prove that A (B C) = (A B) (A C). To prove S = T, where S and T are sets, prove that each set is a subset of the other. To prove S T, prove that if any element x is in S then it is in T. You may not use logical equivalences in your proof. Use general proof techniques like proof by contradiction and proof by cases.
