Prove that sqrt 3 is an irrational Number
Sqrt 3 as a decimal goes on forever... and ever... and ever... with no repeating sequences, which makes it irrational
lols that's nice @glitter_owl but unfortunately that's not a proof. I will probably do it with Reductio ad absurdum but since is already stated @hba I wold attempt another apporach. Square root of any prime is irrational. Proof: http://www.proofwiki.org/wiki/Square_Root_of_any_Prime_is_Irrational 3 is divisible by 1 and 3, hence it's prime. Hence QED.
