\(\sqrt{2}\) के प्रमाण में \(b^2=2r^2\) मिलने पर (b) के बारे में क्या सही है?
In the proof of \(\sqrt{2}\), after getting \(b^2=2r^2\), what is true about (b)?

Correct Answer
C. (b) सम है(b) is even
Concept
\(b^2\) is even, so (b) is also even. This makes both numbers even and gives contradiction.
Why this answer is correct
The correct answer is C. (b) सम है / (b) is even. \(b^2\) is even, so (b) is also even. This makes both numbers even and gives contradiction.
Exam Tip
\(b^2\) सम है इसलिए (b) भी सम होगा। यही दोनों को सम बनाकर विरोधाभास देता है।
