Irrationality of sqrt(n)For a math class, advanced calculus, a homework assignment was to show that the √5 is irrational. I took it a step further. I first tried looking a proof for it up on the web, but it I couldn't find any that didn't have serious errors which made the whole attempt invalid. Let me know if you find any errors in this.

So we'll go ahead and do that now..." #2 20060127 01:30:09
Re: Irrationality of sqrt(n)looks okay to me... The greatest challenge to any thinker is stating the problem in a way that will allow a solution. Bertrand Russell #3 20060204 21:01:07
Re: Irrationality of sqrt(n)Very good proof. I think it's ok too. IPBLE: Increasing Performance By Lowering Expectations.
