Question 1/1 Easy Mathematics Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 17

\(\sqrt{3}\) के प्रमाण में \(9k^2=3b^2\) से क्या सही निष्कर्ष मिलता है?

In the proof of \(\sqrt{3}\), what correct conclusion follows from \(9k^2=3b^2\)?

Explanation opens after your attempt
Correct Answer

A. \(b^2=3k^2\)

Step 1

Concept

Divide both sides of \(9k^2=3b^2\) by (3).

Step 2

Why this answer is correct

We get \(3k^2=b^2\), that is \(b^2=3k^2\).

Step 3

Exam Tip

Then conclude that (b) is divisible by (3). चरण 1: \(9k^2=3b^2\) में दोनों ओर (3) से भाग करें। चरण 2: \(3k^2=b^2\) मिलेगा, यानी \(b^2=3k^2\)। चरण 3: फिर (b) के (3) से विभाज्य होने का निष्कर्ष लें।
