Medium Mathematics Chapter 1: Real Numbers Class 10 Level 16

कौन सा विकल्प \(\sqrt{2}\) की सिद्धि में परिमेय संख्या की परिभाषा का सही उपयोग है?

Which option is the correct use of the definition of rational number in the proof of \(\sqrt{2}\)?

Explanation opens after your attempt
Correct Answer

A. \(\sqrt{2}=\frac{p}{q}\), जहां (p), (q) पूर्णांक हैं और \(q\neq 0\)\(\sqrt{2}=\frac{p}{q}\), where (p), (q) are integers and \(q\neq 0\)

Step 1

Concept

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

Step 2

Why this answer is correct

The denominator cannot be zero, so \(q\neq 0\) is necessary.

Step 3

Exam Tip

In lowest form, (p) and (q) are also taken coprime. चरण 1: परिमेय संख्या दो पूर्णांकों के अनुपात के रूप में लिखी जाती है। चरण 2: हर शून्य नहीं हो सकता, इसलिए \(q\neq 0\) जरूरी है। चरण 3: सबसे सरल रूप में (p) और (q) सहअभाज्य भी लिए जाते हैं।
