Expert Mathematics Chapter 1: Real Numbers Class 10 Level 18

यदि \(\sqrt{3}\) की अपरिमेयता में (p=3r) सिद्ध हो चुका है, तो आगे (q) पर निष्कर्ष निकालने के लिए कौन-सा कदम सही है?

If (p=3r) has been proved in the irrationality proof of \(\sqrt{3}\), which step is correct to conclude about (q)?

Explanation opens after your attempt
Correct Answer

A. (p=3r) को \(p^2=3q^2\) में रखकर \(q^2=3r^2\) पानाSubstitute (p=3r) in \(p^2=3q^2\) to get \(q^2=3r^2\)

Step 1

Concept

Substitute (p=3r) in the original equation.

Step 2

Why this answer is correct

From \(9r^2=3q^2\), we get \(q^2=3r^2\), so \(3\mid q\).

Step 3

Exam Tip

Do not conclude about (q) without substitution. चरण 1: (p=3r) को मूल समीकरण में रखना होगा। चरण 2: \(9r^2=3q^2\) से \(q^2=3r^2\) मिलता है, इसलिए \(3\mid q\)। चरण 3: बिना प्रतिस्थापन किए (q) पर निष्कर्ष न लिखें।
