If
\(\sqrt{3}=\frac{p}{q}\) is assumed in lowest terms to prove its irrationality, which fact produces the contradiction?

Answer and explanation

Correct answer: Both \(p\) and \(q\) are proved divisible by 3.

From \(p^2=3q^2\), 3 divides \(p^2\), so 3 divides \(p\). Substitution then shows that 3 also divides \(q\), contradicting lowest terms. Exam tip: use the prime-factor property for a square.
