\(\sqrt{2}\) के प्रमाण में यदि (a=2r) रखने के बाद \(b^2=2r^2\) मिलता है तो यह किस बात को आगे सिद्ध करता है?
In the proof of \(\sqrt{2}\), if after taking (a=2r) we get \(b^2=2r^2\), what does it prove next?

Correct Answer
A. (b) सम है(b) is even
Concept
\(b^2\) is even so (b) is also even. This creates the contradiction that both (a) and (b) are even.
Why this answer is correct
The correct answer is A. (b) सम है / (b) is even. \(b^2\) is even so (b) is also even. This creates the contradiction that both (a) and (b) are even.
Exam Tip
\(b^2\) सम है इसलिए (b) भी सम होगा। यह (a) और (b) दोनों के सम होने का विरोधाभास बनाता है।
