In the questions of this problem, we will need you to use the definitions of the various set theory operators in terms of propositional logical identities to prove Set Theory identities. Tables 6, 7, 8 of section 1.3 in your textbook will be helpful for you. To give you an example, for two arbitrary sets A, b U , heres a proof of one of two De Morgans identity laws for sets:
Prove the following set identities using the axioms of set theory, propositional logic, as well as the semantics of the membership operator () as exemplified above.
