# Prove that square root of 2 plus square root of 3 is irrational.

I will do a proof by contradiction assume 3sqrt2 is rational then it can be expressed as a ratio, a fraction 3sqrt2=p/q sqrt2=p/q-3 sqrt2=p/q-3q/q sqrt2=p-3q/q since p and q are positive integers, p-3q is also a positive integer. 2011/10/21 · Therefore, sqrt2sqrt3 is irrational 0 2 2 Anon E.
