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)) ?
