Proof that the square root of 2 is irrational

[QUOTE="jedishrfu, post: 5802207, member: 376845"] This discussion may help: [URL]http://mathforum.org/library/drmath/view/52612.html[/URL] Basically, we start by assuming that ##\sqrt{2}## is rational then we can conclude that there exists a fully reduced ratio of integers p/q that represent it. From there the proof goes on to show that p/q isn't fully reduced. It's a key part of the proof. You could start with that notion and then state that there is a common factor to the top and bottom that can be factored out to get a reduced ratio but it is just a side show and it just detracts from the elegance of the proof. But wait until other mentors reply to get their opinion. [/QUOTE]
