Answer 1

Answer:

If √2 could be written as a rational number, the consequence would be absurd. So it is true to say that √2 cannot be written in the form p/q. Hence √2 is not a rational number. Thus, Euclid succeeded in proving that √2 is an Irrational number.

Answer 2

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. ... If 2 is a rational number, then we can express it as a ratio of two integers.
