Math Problem Statement

Does what I said make sense in this context "No rational number c satisfies c 3 = 2. Therefore, 3 square root 2 is irrational. Assume 3 square root 2 = pq\frac{p}{q}. We'd have to then divide the equation by 3 so 2\sqrt2 = p3q\frac{p}{3q}However, this means that square root of 2 is a rational number which is a contradiction. It is well known that 2 \sqrt{2\text{ }}is irrational , therefore 3 square root of 2 must be irrational
