[quote name='eldad9']Prove or disprove: there are no positive integers x, y, and z such that x**n + y**n = z**n where n is a natural number greater than 2.
(** stands for power, that is, 2**3 = two to the third = 8)[/QUOTE]
Oh okay, this ones easy. say x = 3, y = -2 and z = 0. if you take the 3 and muliply it by the ABSOLUTE VALUE of -2, that is to say, 2, then you will have 6. after you get this 6, look it at carefully. if it doesn't respond with a glimmer of hope, then go jump off a bridge, because life is not worth living. If you get a remainder, go back and check the absolute value, which should be somewhere on the ummmmm number line. if it's not on the number line, then I think that means your sexual preferences are in fluctuation and that you must foil out two to the third, according to the side angle side theorem. If you don't successfully foil, then try picking up a random chick at the bar and giving her a pink sock. Take a pic, post it in this thread to prove your answer.
Hope that helps ;-)
