Are the statement forms P∨((Q∧R)∨ S) and ¬((¬ P)∧(¬(Q∧ R)∧ (¬ S))) logically equivalent? I found that they were not logically equivalent but wanted to check. Also, does the negation outside the parenthesis on the second statement form cancel out with the negation in front of P and in front of (Q∧ R)∧ (¬ S)) ?

(1) Determine whether the propositions p → (q ∨ ¬r) and (p ∧ ¬q) → ¬r are logically equivalent using either a truth table or laws of logic. (2) Let A, B and C be sets. If a is the proposition “x ∈ A”, b is the proposition “x ∈ B” and c is the proposition “x ∈ C”, write down a proposition involving a, b and c that is logically equivalentto“x∈A∪(B−C)”. (3) Consider the statement ∀x∃y¬P(x,y). Write down a...

Using the laws of propositional equivalence,  show that  p → p ∧ ( p → q) is logically equivalent to p → q. That means a chain of equivalences starting with the first expression and ending with p → q. Remember: The connective ∧ has higher precedence than the connective → so be sure to parse the original expression correctly! To start you off here's a possible first step. p → p ^ ( p → q) ≡   p → p ^...
