Easy Mathematics Chapter 1: Real Numbers Class 10 Level 16

(p=3k) को \(p^2=3q^2\) में रखने पर कौन सा सही निष्कर्ष मिलता है?

What correct conclusion is obtained by putting (p=3k) in \(p^2=3q^2\)?

Explanation opens after your attempt
Correct Answer

A. \(q^2=3k^2\), इसलिए (q) (3) से विभाज्य है\(q^2=3k^2\), so (q) is divisible by (3)

Step 1

Concept

Putting (p=3k) gives \(p^2=9k^2\).

Step 2

Why this answer is correct

From \(9k^2=3q^2\), we get \(q^2=3k^2\), so (q) is also divisible by (3).

Step 3

Exam Tip

A common factor breaks the coprime condition. चरण 1: (p=3k) रखने पर \(p^2=9k^2\) मिलता है। चरण 2: \(9k^2=3q^2\) से \(q^2=3k^2\), इसलिए (q) भी (3) से विभाज्य है। चरण 3: साझा गुणनखंड मिलने पर सहअभाज्य शर्त टूटती है।
