किस विकल्प में \(\sqrt{2}\) के प्रमाण की गलत जल्दबाजी दिखाई गई है?
Which option shows a wrong shortcut in the proof of \(\sqrt{2}\)?
Explanation opens after your attempt
Correct Answer
D. \(m^2=2n^2\) से सीधे (m=2n)From \(m^2=2n^2\), directly (m=2n)
Concept
The square relation does not directly give (m=2n). The correct conclusion first is only that (m) is even.
Why this answer is correct
The correct answer is D. \(m^2=2n^2\) से सीधे (m=2n) / From \(m^2=2n^2\), directly (m=2n). The square relation does not directly give (m=2n). The correct conclusion first is only that (m) is even.
Exam Tip
वर्ग संबंध से सीधे (m=2n) नहीं मिलता। सही निष्कर्ष पहले केवल (m) का सम होना है।
