Complete a truth table to show that (PvvQ)->R is logically equivalent to (P->R)^(^())(Q->R). Suppose that you are trying to prove a statement that is written in the form (PvvQ)->R. Explain why you can complete this proof by writing separate and independent proofs of P->R and Q->R. Now consider the following proposition: Proposition. For all integers x and y, if xy is odd, then x is odd and y is odd. Write the contrapositive of this proposition. 4. Now prove that if x is an even integer, then xy is an even integer. Also, prove that if y is an even integer, then xy is an even integer. 5. Use the results proved in part (4) and the explanation in part (2) to explain why we have proved the contrapositive of the proposition in part (3).
