Proof: By contradiction; assume n2 is even but n is odd. Since n is odd, n = 2k + 1 for some integer k. Then n2 = (2k + 1)2 = 4k2 + 4k + 1 = 2(2k2 + 2k) + 1. Now, let m = 2k2 + 2k. Then n2 = 2m + 1, so by definition n2 is even. But this is clearly impossible, since n2 is even. harvin punter

Thus, on this assumption, √ 2 can be expressed in the form p/q, where at least one of p and q is odd. Since p/q =√ 2 we can square both sides to get: p 2 q 2 = 2 Multiplying both sides by q 2, we get p 2 = 2q 2. http://www.holispsych.com/theory/motivation/examples-of-direct-and-indirect-motivation.html
