\(\sqrt{5}\) के प्रमाण में कौन सा चरण गलत है?

Which step is wrong in the proof of \(\sqrt{5}\)?

Explanation opens after your attempt
Correct Answer

A. \(p^2=5q^2\) से (p=5q) लिखनाWriting (p=5q) from \(p^2=5q^2\)

Step 1

Concept

From \(p^2=5q^2\), we get that \(p^2\) is divisible by (5).

Step 2

Why this answer is correct

We cannot directly write (p=5q).

Step 3

Exam Tip

The correct step is to say (p) is divisible by (5), then write (p=5k). चरण 1: \(p^2=5q^2\) से यह मिलता है कि \(p^2\) (5) से विभाज्य है। चरण 2: इससे सीधे (p=5q) नहीं लिख सकते। चरण 3: सही कदम है कि (p) (5) से विभाज्य है, फिर (p=5k) लिखें।
