Hard Mathematics Chapter 1: Real Numbers Class 10 Level 16

\(\sqrt{3}\) की सिद्धि में \(p^2=3q^2\) से (p=3k) और फिर (q=3r) मिला। इससे मूल मान्यता क्यों गलत होती है?

In the proof of \(\sqrt{3}\), \(p^2=3q^2\) gives (p=3k) and then (q=3r). Why does this make the original assumption false?

Correct Answer

A. क्योंकि \(\frac{p}{q}\) सरलतम रूप में माना गया था, पर (3) साझा गुणनखंड मिल गयाBecause \(\frac{p}{q}\) was assumed in lowest form, but common factor (3) was found

Step 1

Concept

In the rational assumption, \(\frac{p}{q}\) was taken in lowest form.

Step 2

Why this answer is correct

(p=3k) and (q=3r) show common factor (3) in both.

Step 3

Exam Tip

This contradicts lowest form, so the rational assumption is false. चरण 1: परिमेय मान्यता में \(\frac{p}{q}\) को सरलतम रूप में लिया गया था। चरण 2: (p=3k) और (q=3r) बताता है कि (p) और (q) दोनों में (3) साझा है। चरण 3: यह सरलतम रूप से विरोधाभास है, इसलिए परिमेय मान्यता गलत है।
