Re: Getting into coding with a PhD in math

It is also true that |a|=|b| for the same reason, though they are not necessarily equal to 1. One of the known proofs that the square root of 2 is irrational reaches contradiction through 2m^2=n^2 Right, that I know, it was just the generalization to two squarefree numbers that I had a hiccup on.

Squarefree number property

This is not homework, merely a curiosity I came across.

I encountered the statement "If am2=bn2, where a,b are squarefree integers and m,n are integers such that gcd(m,n) = 1, then |m|=|n|=1."

However, I am having difficulty seeing the reasoning behind this statement.
