Suppose \(\sqrt{3}=\frac{a}{b}\), where \(a\) and \(b\) are coprime positive integers. Which contradiction follows from this assumption?

Answer and explanation

Correct answer: \(a\) और \(b\) दोनों 3 से विभाज्य हैं

From \(a^2=3b^2\), 3 divides \(a^2\), so the prime-divisibility property gives \(3\mid a\). Put \(a=3k\) to obtain \(3\mid b\) too, contradicting coprimality. In exams, state the prime-divisibility step clearly.
