hi well I'm having truple in proving this (sqrt(2))^3 is irrational number!
The discussion centers on proving that \((\sqrt{2})^3\) is an irrational number. Participants reference Euclid's proof of the irrationality of \(\sqrt{2}\) and emphasize that if \(a\) is a rational number, then \(a^3\) must also be rational. The conversation suggests that the proof can be approached through mathematical reasoning rather than solely relying on computer science tools. Key resources provided include links to Wikipedia and a personal essay on the topic.

It should be very simple to prove that if a is a rational number, then so it a3. Do you know Euclid's proof that \sqrt{2} is irrational?
