WebCommutative for: (˄) and for: (˅) (P˄Q) → (Q˄P) (P˅Q) → (Q˅P) The truth values in the last column are all TRUE (T), therefore the statement (P˄Q) → (Q˄P) is a tautology. WebWe now use one of the rules of De Morgan: 12. -(pv q) V -(-pVr) Vq Vr = (PA -q) V (PA -r) V qVr 2 13. Using the rule p - q = -p V q, we rewrite the given expression as 14. We now distribute inside each parenthesis and use one of the identity laws: 15. Using De Morgan again, we get 16. To prove the validity of resolution, we need to show that (p ...
