It is irrelevant that the condition is now false. Therefore these two consecutive integers cannot both be perfect squares. One is the following question: Note that John and Diana are telling the truth as well here, and it is Carlos who is lying.

If it is not true than m is even or n is even, then m and n are both odd. Therefore p and r are logically equivalent. The following drawing rotated as necessary shows that we can tile the board using straight triominoes if one of those four squares is removed. Clearly there are no integer solutions to these equations, so there are no solutions to the original equation.

The statement of the problem is really the solution. We will use the male pronoun in what follows, assuming that we are talking about males shaving their beards here, and assuming that all men have facial hair.

This is, according to Table 1, disjunctive syllogism. The logical expression is asserting that the domain consists of at most two members. Some will be placed horizontally and some vertically. The conditional statement will be true if p is false, or if q in one case or r in the other case is true, i.

Therefore any domain having one or two members will make it true such as the female members of the United States Supreme Court inand any domain with more than two members will make it false such as all members of the United States Supreme Court in In all of these, we will let Y x be the propositional function that x is in your school or class, as appropriate.

The product of two with the same sign is nonnegative. The number 1 has this property, since the only positive integer not exceeding 1 is 1 itself, and therefore the sum is 1. Then the given information can be expressed symbolically as follows: Can none of them be guilty? For parts a and b we have the following table column two for part acolumn four for part b.

In English, some student has solved at least one exercise in every section of this book.

An conditional statement in which the conclusion is true or the hypothesis is false solutios true, and that completes the argument. Now suppose that A is false. Therefore we must substitute these values back into the original equation to determine whether they do indeed satisfy it. Following the idea and syntax of Example 28, we have the following rule: In each case we need to specify some propositional functions predicates and identify the domain of discourse.

## CHEAT SHEET

If P x is true for all xthen the left-hand side is true. This system is consistent. Let m be the square root of n, rounded down if it is not a whole number. Alternatively, some hopping animals are rabbits.

Let W r means that room r is painted white. Since P x0 is false, it must be the case that Q y is true for each y. The variable s ranges over students in the class, the variable c ranges over the four class standings, and the variable m ranges over all possible majors. The other parts of this exercise are similar.

So suppose that n is not even, i. Therefore Jones is the murderer. But this is obviously not true. The third sentence says that if you eat x, then x tastes good. Help Center Find new research papers in: We write these symbolically: Therefore Alice is telling the truth, so Carlos did it. We must show editoon Tweety is small. We follow the hint. In what follows y represents an arbitrary person. This conditional statement fails in the case in which s is true and e is false.

Having exhausted the possibilities, we conclude that no cube less than is the sum of 6h cubes.

The given statement tells us that there are exactly two elements in the domain. We must show that whenever we have two even integers, their sum is even. Our domain of discourse for persons here consists of people in this class. On the other hand, if he does not shave himself, then the rule says that he must shave himself. There are no conclusions to be drawn about Maggie.

Thus this string of letters, while appearing to be a proposition, is in fact meaningless. It now follows from the second part of the hypothesis that r is true, as desired.
