Use propositional logic to prove that the argument is valid. (A + B) ^ [A + (B + C)] ( AC) Use propositional logic to prove that the argument is valid. (A / B) + (A B')' Use propositional logic to prove the validity of the arguments in Exercises 25-33. These will become additional derivation rules for propositional logic, summarized in Table 1.14 (P +Q) +(Q' + P') * Do not use contraposition rule directly. This question is to prove the contraposition rule
