Correct Answer

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

Step 1

Concept

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

Step 2

Why this answer is correct

This proves both (p) and (q) even.

Step 3

Exam Tip

Both even contradict the coprime condition. चरण 1: \(\sqrt{2}\) के प्रमाण में \(p^2=2q^2\) मिलता है। चरण 2: इससे (p) और (q) दोनों सम सिद्ध होते हैं। चरण 3: दोनों सम होना सहअभाज्य शर्त से विरोधाभास है।
