Correct Answer

A. परिमेय मानें, वर्ग करें, दोनों सम पाएं, सहअभाज्य से विरोधाभासAssume rational, square, find both even, contradict coprime

Step 1

Concept

Assume \(\sqrt{2}\) rational and write it as \(\frac{p}{q}\).

Step 2

Why this answer is correct

Squaring leads to both (p) and (q) being even.

Step 3

Exam Tip

Both even contradict the coprime condition. चरण 1: \(\sqrt{2}\) को परिमेय मानकर \(\frac{p}{q}\) लिखते हैं। चरण 2: वर्ग करने पर दोनों (p) और (q) सम निकलते हैं। चरण 3: दोनों सम होना सहअभाज्य शर्त से विरोधाभास देता है।
