Hard Mathematics Chapter 1: Real Numbers Class 10 Level 16

\(\sqrt{5}\) की सिद्धि में यदि (p) और (q) दोनों (5) से विभाज्य सिद्ध हो जाएं, तो कौन सा निष्कर्ष सबसे अधिक तार्किक है?

In the proof of \(\sqrt{5}\), if both (p) and (q) are proved divisible by (5), which conclusion is the most logical?

Correct Answer

A. \(\frac{p}{q}\) सरलतम रूप में नहीं था, इसलिए परिमेय मान्यता असंभव है\(\frac{p}{q}\) was not in lowest form, so the rational assumption is impossible

Step 1

Concept

If both are divisible by (5), numerator and denominator have common factor (5).

Step 2

Why this answer is correct

Such a situation cannot occur in lowest form.

Step 3

Exam Tip

Therefore the rational assumption is impossible and \(\sqrt{5}\) is irrational. चरण 1: दोनों (5) से विभाज्य हैं, इसलिए अंश और हर में (5) साझा गुणनखंड है। चरण 2: सरलतम रूप में ऐसी स्थिति नहीं हो सकती। चरण 3: इसलिए परिमेय मान्यता असंभव है और \(\sqrt{5}\) अपरिमेय है।
