किस विकल्प में \(\sqrt{2}\) को परिमेय मानने के बाद सही विरोधाभासी परिणाम है?

Which option gives the correct contradictory result after assuming \(\sqrt{2}\) rational?

Explanation opens after your attempt
Correct Answer

A. (2) अंश और हर दोनों का साझा गुणनखंड बन जाता है(2) becomes a common factor of both numerator and denominator

Step 1

Concept

We assume \(\sqrt{2}=\frac{p}{q}\), where (p,q) are coprime.

Step 2

Why this answer is correct

The proof shows both (p) and (q) are even.

Step 3

Exam Tip

Thus (2) becomes a common factor, contradicting coprimality. चरण 1: \(\sqrt{2}\) को \(\frac{p}{q}\) मानते हैं, जहाँ (p,q) सहअभाज्य हैं। चरण 2: प्रमाण से (p) और (q) दोनों सम निकलते हैं। चरण 3: इसलिए (2) साझा गुणनखंड बनता है, जो सहअभाज्यता के विरुद्ध है।
