Prove that 2√ is irrational.​

Answer 1

Answer:

To prove that the square root of 2 is irrational is to first assume that its negation is true. Therefore, we assume that the opposite is true, that is, the square root of 2 is rational. ... So, 2 = a b \sqrt 2 = {\Large{{a \over b}}} 2 =ba where a and b are integers but b ≠ 0 b \ne 0 b=0.
