Medium Mathematics Chapter 1: Real Numbers Class 10 Level 16

एक प्रमाण में \(p^2=2q^2\) से (p=2r) और फिर (q=2s) मिला। यह कौन सा विरोधाभास देता है?

In a proof, from \(p^2=2q^2\), we get (p=2r) and then (q=2s). What contradiction does this give?

Explanation opens after your attempt
Correct Answer

A. (p) और (q) सहअभाज्य नहीं हैं(p) and (q) are not coprime

Step 1

Concept

(p=2r) and (q=2s) mean both are divisible by (2).

Step 2

Why this answer is correct

So they cannot be coprime.

Step 3

Exam Tip

But they were assumed coprime at the start, which is the contradiction. चरण 1: (p=2r) और (q=2s) से दोनों (2) से विभाज्य हैं। चरण 2: इसलिए वे सहअभाज्य नहीं हो सकते। चरण 3: जबकि शुरुआत में उन्हें सहअभाज्य माना गया था, यही विरोधाभास है।
