6. Show the validity of the logical equivalence: ¬(p↔q) = ¬p↔ q

Using appropriate logical equivalences, show that (watch the brackets), ((P ⇒ Q) ^ (Q ⇒ P))' = ((P VQ) ^ (P' V Q')) by starting with Q ⇒ P))' = ((P⇒Q) ^ (Q⇒ and then transforming this appropriately, referencing a required logical equivalence at each step. Use one logical equivalence per step only.
