I wih prove (sqrt(2))^3 is irrational number

Click For Summary
SUMMARY

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.

PREREQUISITES
  • Understanding of irrational numbers and their properties
  • Familiarity with Euclid's proof of the irrationality of \(\sqrt{2}\)
  • Basic knowledge of mathematical proofs and logic
  • Ability to manipulate algebraic expressions involving square roots
NEXT STEPS
  • Study Euclid's proof of the irrationality of \(\sqrt{2}\)
  • Learn about properties of exponents and their implications for rationality
  • Explore mathematical proof techniques, particularly proof by contradiction
  • Investigate the function Irrational_check and its application in proving irrationality
USEFUL FOR

Students of mathematics, educators teaching number theory, and anyone interested in understanding the properties of irrational numbers and mathematical proofs.

hi well I'm having truple in proving this (sqrt(2))^3 is irrational number!
 
Computer science news on Phys.org
If you think this can be proved by computer science, I can see why!

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?
 
well i need to prove the whole statement step by step how u proved it is irrational!
 
use Irrational_check(sqrt(2)^3)
