Step 1

1. \( p \lor (q \land r) \) and \( (p \lor q) \land (p \lor r) \) - Apply the distributive law of logic: \( p \lor (q \land r) \equiv (p \lor q) \land (p \lor r) \) - Therefore, these two statements are logically equivalent. 2. \( \neg (\neg p \rightarrow Show more…

Determine whether each pair of statements is logically equivalent. 1. p v (q ^ r) and (p v q) ^ (p v r) 2. ~(~p -> q) and p -> ~q 3. ~(p ^ q) and (~p) v (~q) Write the negation of the given statement in its equivalent conjunctive form. "If x is an odd integer, then x^2 is an odd integer."
