Correct Answer

A. \(\sqrt{2}\) की अपरिमेयता के प्रमाण मेंIn the proof of irrationality of \(\sqrt{2}\)

Step 1

Concept

In the proof of \(\sqrt{2}\), we get \(p^2=2q^2\).

Step 2

Why this answer is correct

This makes both (p) and (q) divisible by (2), that is even.

Step 3

Exam Tip

The common factor (2) creates the contradiction. चरण 1: \(\sqrt{2}\) के प्रमाण में \(p^2=2q^2\) मिलता है। चरण 2: इससे (p) और (q) दोनों (2) से विभाज्य यानी सम मिलते हैं। चरण 3: (2) वाला साझा गुणनखंड विरोधाभास बनाता है।
