I have a lot of questions and am very confused.

First on number 1 part c, how do we begin the proof when there is nothing said about "divides" in the "P" but there is in the "Q"?

Second, on 1 part d, does the square root effect the outcome somehow?

Third, I am not sure how to fill out the "If Q, then P" and "If not P, then not Q" portions of the truth table.

Finally, for number 3 do you want a mathematical example or just a real life example in which the inverse and converse are not neccessarily true?

Sorry for all the questions.
