Are the statements P → Q ∨ R and P → Q ∨ P → R logically equivalent?
1.3. 24 Show that (p → q) ∨ (p → r) and p → (q ∨ r) are logically equivalent. By the definition of conditional statements on page 6, using the Com- mutativity Law, the hypothesis is equivalent to (q ∨ ¬p) ∨ (¬p ∨ r). By the Associative Law, this is equivalent to ((q ∨ ¬p) ∨ ¬p) ∨ r, and hence to (q ∨ (¬p ∨ ¬p)) ∨ r.
