Medium Mathematics Chapter 1: Real Numbers Class 10 Level 16

यदि \(\sqrt{2}\) को परिमेय मानने से अंत में (q=2s) मिले, तो प्रमाण में यह क्यों महत्वपूर्ण है?

If assuming \(\sqrt{2}\) rational finally gives (q=2s), why is this important in the proof?

Correct Answer

A. क्योंकि इससे (q) सम सिद्ध होता है और (p) पहले ही सम थाBecause it proves (q) even and (p) was already even

Step 1

Concept

First (p) is proved even in the proof.

Step 2

Why this answer is correct

If (q=2s), then (q) is also even.

Step 3

Exam Tip

Both even gives common factor (2) and creates a contradiction. चरण 1: प्रमाण में पहले (p) सम सिद्ध किया जाता है। चरण 2: यदि (q=2s) मिल गया, तो (q) भी सम है। चरण 3: दोनों सम होने से (2) साझा गुणनखंड मिलता है और विरोधाभास बनता है।
