Yup, more maths...(kind of urgent now)
Show that sqrt(n) is irrational if n is a positive integer that is not a perfect square.
(Note: Integer n is a perfect square if n = k^2 for some integer k. Hint: use a proof by contradiction, together with the Fundamental Theorem of Arithmetic)
Um, I'm lost, and I need to show this in ~2 hours
Thanks if you can help in time,
Paul.
