Expert Mathematics Chapter 1: Real Numbers Class 10 Level 18

\(\sqrt{3}\) की अपरिमेयता सिद्ध करते समय \(q\neq0\) लिखना क्यों आवश्यक है?

Why is it necessary to write \(q\neq0\) while proving the irrationality of \(\sqrt{3}\)?

Explanation opens after your attempt
Correct Answer

A. क्योंकि हर शून्य होगा तो \(\frac{p}{q}\) परिभाषित नहीं होगाBecause if the denominator is zero, \(\frac{p}{q}\) is not defined

Step 1

Concept

The rational form \(\frac{p}{q}\) is valid only when \(q\neq0\).

Step 2

Why this answer is correct

If the denominator is zero, the fraction is not defined.

Step 3

Exam Tip

This condition must be written at the beginning of the proof. चरण 1: परिमेय संख्या का रूप \(\frac{p}{q}\) तभी मान्य है जब \(q\neq0\)। चरण 2: हर शून्य होने पर भिन्न परिभाषित नहीं रहती। चरण 3: प्रमाण की शुरुआत में यह शर्त लिखना जरूरी है।
