Hard Mathematics Chapter 1: Real Numbers Class 10 Level 18

\(\sqrt{2}\) की अपरिमेयता सिद्ध करते समय \(\frac{p}{q}\) को सबसे सरल रूप में लेना क्यों जरूरी है?

Why is it necessary to take \(\frac{p}{q}\) in lowest form while proving the irrationality of \(\sqrt{2}\)?

Correct Answer

A. ताकि अंत में साझा गुणनखंड मिलना विरोधाभास बनेSo that getting a common factor at the end becomes a contradiction

Step 1

Concept

A rational number is written in lowest form as \(\frac{p}{q}\).

Step 2

Why this answer is correct

The proof shows that both (p) and (q) become even, which contradicts lowest form.

Step 3

Exam Tip

Always mention coprime at the start of the proof. चरण 1: परिमेय संख्या को सबसे सरल रूप में \(\frac{p}{q}\) माना जाता है। चरण 2: प्रमाण में (p) और (q) दोनों सम निकलते हैं, जो सबसे सरल रूप के विरुद्ध है। चरण 3: शुरुआत में सहअभाज्य लिखना बहुत जरूरी है।
