\(\sqrt{2}\) के प्रमाण में \(p^2=2q^2\) से सीधे क्या नहीं कहना चाहिए?
In the proof of \(\sqrt{2}\), what should not be said directly from \(p^2=2q^2\)?
Explanation opens after your attempt
Correct Answer
A. (p=q)
Concept
From \(p^2=2q^2\), we get that \(p^2\) is even.
Why this answer is correct
Then (p) is even and can be written as (p=2k).
Exam Tip
Saying (p=q) from this equation is a wrong step. चरण 1: \(p^2=2q^2\) से \(p^2\) सम मिलता है। चरण 2: फिर (p) सम और (p=2k) लिखा जा सकता है। चरण 3: इस समीकरण से (p=q) कहना गलत कदम है।
