\(\sqrt{2}\) के प्रमाण में (m=2k) रखने पर \(m^2=2n^2\) से कौन-सा सही संबंध प्राप्त होता है?
In the proof of \(\sqrt{2}\), after taking (m=2k), which correct relation is obtained from \(m^2=2n^2\)?
Explanation opens after your attempt
Correct Answer
A. \(n^2=2k^2\)
Concept
Putting (m=2k) gives \(4k^2=2n^2\). Simplifying gives \(n^2=2k^2\).
Why this answer is correct
The correct answer is A. \(n^2=2k^2\). Putting (m=2k) gives \(4k^2=2n^2\). Simplifying gives \(n^2=2k^2\).
Exam Tip
(m=2k) रखने पर \(4k^2=2n^2\) बनता है। सरल करने पर \(n^2=2k^2\) मिलता है।
