Easy Mathematics Chapter 1: Real Numbers Class 10 Level 17

कौन सा विकल्प \(\sqrt{3}\) की अपरिमेयता का सही संक्षिप्त कारण है?

Which option is the correct short reason for the irrationality of \(\sqrt{3}\)?

Explanation opens after your attempt
Correct Answer

A. परिमेय मानने पर अंश और हर दोनों (3) से विभाज्य हो जाते हैंAssuming rational makes both numerator and denominator divisible by (3)

Step 1

Concept

Assuming \(\sqrt{3}=\frac{a}{b}\) and squaring gives \(a^2=3b^2\).

Step 2

Why this answer is correct

This makes both (a) and (b) divisible by (3).

Step 3

Exam Tip

This is impossible in a lowest-form fraction. चरण 1: \(\sqrt{3}\) को \(\frac{a}{b}\) मानकर वर्ग करने पर \(a^2=3b^2\) मिलता है। चरण 2: इससे (a) और (b) दोनों (3) से विभाज्य हो जाते हैं। चरण 3: सरलतम भिन्न में ऐसा होना असंभव है।
