किस विकल्प में \(\sqrt{2}\) के प्रमाण की बीजगणितीय कड़ी सही है?
Which option shows the correct algebraic chain in the proof of \(\sqrt{2}\)?
Explanation opens after your attempt
Correct Answer
A. \(a^2=2b^2\), (a=2r), \(b^2=2r^2\)
Concept
In the proof of \(\sqrt{2}\), the chain uses evenness by (2). This chain shows (b) is also even.
Why this answer is correct
The correct answer is A. \(a^2=2b^2\), (a=2r), \(b^2=2r^2\). In the proof of \(\sqrt{2}\), the chain uses evenness by (2). This chain shows (b) is also even.
Exam Tip
\(\sqrt{2}\) के प्रमाण में (2) से समता की कड़ी बनती है। यह कड़ी (b) को भी सम दिखाती है।
