WebSep 29, 2016 · sqrt(33) is irrational To add a proof to the existing answer: A rational number is a real number which can be expressed as the ratio of two integers. That is, x is rational if and only if x = a/b where a and b are integers and b!=0. Now, suppose sqrt(33) is rational. Then sqrt(33) = a/b for some integers a and b. Then, squaring both sides, we get … WebBy assuming that √2 is rational, we were led, by ever so correct logic, to this contradiction. So, it was the assumption that √2 was a rational number that got us into trouble, so that assumption must be incorrect, which means that √2 must be irrational. Here is a link to some other proofs by contradiction:
