Supplementary Exercises 33 Since q 3 is even, q must be even.

One such assignment is T for p and F for q and r. Updated Jan 7, If Jones and Williams are the innocent truth-tellers, then we again get a contradiction, since Jones says that he did not know Cooper and was out of town, but Williams says he saw Jones with Cooper presumably in town, and presumably if we was with him, then he knew him.

This is a nonconstructive proof—we do not know which of them meets the requirement. This exercise is similar to Exercise Sep 15, Alex Amigos added it.

Let m be the square root of n, rounded down if it is not a whole number. Want to Read saving…. We can let p be true and the other two variables be false.

If the domain consists of all United States Presidents, then the statement is false. Colleen rated it it was ok Oct 24, Therefore the two propositions are logically equivalent.

We need to make up a predicate in each case. Return to Book Page. Mar 04, Manadsawee P-Cento rated it it was amazing. If Smith and Jones are innocent and therefore telling the truththen we get an immediate contradiction, since Smith said that Jones was a friend of Cooper, but Jones said that he did not even know Cooper.

Of these three numbers, at least two must have the same sign both positive or both negativesince there are only two signs.

Logic and Proofs In fact, a computer algebra system will tell us that neither of them is a perfect square. In each case we hunt for truth assignments that make all the disjunctions true. Therefore the conditional statement is true. In the second case, 5thh is smallest or tied for smallest. To view it, click here.

Therefore by universal modus ponens we can conclude that Tweety is richly colored. It cannot be that m is mathematics, since there is no senior mathematics major, and it cannot be that m is computer science, since there is no freshman computer science major. This is 2 times an integer, so it is even, as desired.

If we use all of, andthen we are again quickly forced into a sequence of placements that lead to a contradiction. Mathmatics by modus ponens we know that I see elephants running down the road.

A knight will declare himself to be a knight, telling the truth. In fact, a computer algebra system will tell us that all three are positive, jathematics all three products are positive.
