Homework Statement
Prove that [itex] \sqrt{3} [/itex] is irrational.
The Attempt at a Solution
SO I will start by assuming that [itex] \sqrt{3} [/itex] is rational and i can represent this as
[itex] 3=\frac{b^2}{a^2} [/itex] and I assume that a and b have no common factors.
so now I have [itex] 3b^2=a^2 [/itex]
but this is not possible because if a and b have no common factors.
I probably need to add more to this, what do you guys think?
