\(\sqrt{2}\) के प्रमाण में \(m^2=2n^2\) से सीधे (n) सम लिखना क्यों गलत या अधूरा है?
Why is it wrong or incomplete to write (n) even directly from \(m^2=2n^2\) in the proof of \(\sqrt{2}\)?
Explanation opens after your attempt
Correct Answer
A. पहले (m) सम सिद्ध करके (m=2k) रखना पड़ता हैFirst (m) must be proved even and (m=2k) must be used
Concept
\(m^2=2n^2\) does not directly give (n) even. After putting (m=2k), \(n^2=2k^2\) is obtained.
Why this answer is correct
The correct answer is A. पहले (m) सम सिद्ध करके (m=2k) रखना पड़ता है / First (m) must be proved even and (m=2k) must be used. \(m^2=2n^2\) does not directly give (n) even. After putting (m=2k), \(n^2=2k^2\) is obtained.
Exam Tip
\(m^2=2n^2\) से सीधे (n) सम नहीं मिलता। (m=2k) रखने के बाद \(n^2=2k^2\) मिलता है।
