While proving the irrationality of \(\sqrt{3}\) by contradiction, which situation contradicts the assumption that \(p/q\) is in lowest terms?

Answer and explanation

Correct answer: \(p\) और \(q\) दोनों 3 से विभाज्य हैं

In lowest terms, \(p\) and \(q\) cannot have a common factor. From \(3\mid p^2\), we get \(3\mid p\); substitution then gives \(3\mid q\). Thus 3 is a common factor. Exam tip: use the prime divisibility rule for squares.
