Easy Mathematics Chapter 1: Real Numbers Class 10 Level 17

\(\sqrt{5}\) को परिमेय मानकर \(\sqrt{5}=\frac{m}{n}\) लिखने पर (m) और (n) को सहअभाज्य क्यों लिया जाता है?

Why are (m) and (n) taken as coprime when \(\sqrt{5}\) is assumed rational and written as \(\sqrt{5}=\frac{m}{n}\)?

Correct Answer

A. क्योंकि भिन्न को सरलतम रूप में लिया जाता हैBecause the fraction is taken in lowest form

Step 1

Concept

A rational number is written as a ratio of two integers.

Step 2

Why this answer is correct

In the proof, it is taken in lowest form, so (m) and (n) are coprime.

Step 3

Exam Tip

Later, finding a common factor gives the contradiction. चरण 1: परिमेय संख्या को दो पूर्णांकों के अनुपात में लिखा जाता है। चरण 2: प्रमाण में उसे सरलतम रूप में लेते हैं, इसलिए (m) और (n) सहअभाज्य होते हैं। चरण 3: बाद में साझा गुणनखंड मिलने पर यही बात विरोधाभास देती है।
