Consider the following premises: 1. A ? (B ? A) is a Theorem of Propositional Calculus/Logic (i.e. it's logically valid), for all statement forms A and B. 2. Suppose then that the following are the temporary axioms (assumptions): a) W (axiom 1) b) Y (axiom 2) c) Y ? Z (axiom 3) Using the logical rules of inference, Modus Ponens (MP) and/or Hypothetical Syllogism (HS), show that X ? Z is deducible (i.e. it is a logical/valid conclusion) from the given premises (i.e. 1 and 2).

Use propositional logic to prove that the following argument is valid: (P' ∧ Q') ∧ (R ∨ P') → (Q' ∨ R) (for example, use hyp, modus ponens, etc...)
