Hard Mathematics Chapter 1: Real Numbers Class 10 Level 16

कौन सा विकल्प \(\sqrt{2}\) के प्रमाण में \(\frac{p}{q}\) को सरलतम रूप मानने की भूमिका बताता है?

Which option tells the role of assuming \(\frac{p}{q}\) in lowest form in the proof of \(\sqrt{2}\)?

Explanation opens after your attempt
Correct Answer

A. बाद में (p) और (q) दोनों सम मिलने पर विरोधाभास दिखानाTo show contradiction when both (p) and (q) are later found even

Step 1

Concept

In lowest form, (p) and (q) are coprime.

Step 2

Why this answer is correct

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

Step 3

Exam Tip

Both being even breaks the lowest-form condition. चरण 1: सरलतम रूप में (p) और (q) सहअभाज्य होते हैं। चरण 2: प्रमाण में (p) और (q) दोनों सम निकलते हैं। चरण 3: दोनों सम होना सरलतम रूप की शर्त को तोड़ता है।
