Correct Answer
A. \(\sqrt{3}\) की अपरिमेयता के प्रमाण में / In the proof of irrationality of \(\sqrt{3}\)
Step 1
Concept
Assuming \(\sqrt{3}\) rational gives \(a^2=3b^2\).
Step 2
Why this answer is correct
So factor (3) becomes the main base of the proof.
Step 3
Exam Tip
It shows both (a) and (b) divisible by (3). चरण 1: \(\sqrt{3}\) को परिमेय मानने पर \(a^2=3b^2\) मिलता है। चरण 2: इसलिए (3) का गुणनखंड प्रमाण का मुख्य आधार बनता है। चरण 3: इसी से (a) और (b) दोनों (3) से विभाज्य मिलते हैं।
