Medium Mathematics Chapter 1: Real Numbers Class 10 Level 17

\(\sqrt{5}\) के प्रमाण में (p=5k) रखने के बाद \(25k^2=5q^2\) मिलता है। इससे कौन सा निष्कर्ष सही है?

In the proof of \(\sqrt{5}\), after putting (p=5k), \(25k^2=5q^2\) is obtained. Which conclusion is correct?

Explanation opens after your attempt
Correct Answer

B. \(q^2=5k^2\)

Step 1

Concept

Divide both sides of \(25k^2=5q^2\) by (5).

Step 2

Why this answer is correct

We get \(5k^2=q^2\), that is \(q^2=5k^2\).

Step 3

Exam Tip

This is used to prove (q) is also divisible by (5). चरण 1: \(25k^2=5q^2\) के दोनों पक्षों को (5) से भाग दें। चरण 2: \(5k^2=q^2\), अर्थात \(q^2=5k^2\) मिलेगा। चरण 3: इससे (q) भी (5) से विभाज्य सिद्ध किया जाता है।
