Hey RealFunctionInc, not sure if you're aware or not, but the proof that the square root of 2 is irrational is actually considered as a 2U level question. It's even proven in year 10/prelim HSC 2U textbooks!

Just thought I'd let you know if you didn't! :)

More of a 3U proof by contradiction would be proving that log(2)3 is irrational!
