कौन सा कथन \(\sqrt{5}\) के प्रमाण में सही नहीं है?
Which statement is not correct in the proof of \(\sqrt{5}\)?
Explanation opens after your attempt
Correct Answer
C. \(\sqrt{5}=5\) मान लेते हैंWe take \(\sqrt{5}=5\)
Concept
\(\sqrt{5}=5\) is false because \(5^2=25\).
Why this answer is correct
In the correct proof, \(\sqrt{5}\) is assumed rational and a contradiction is obtained.
Exam Tip
Do not treat a square root as equal to the number under it. चरण 1: \(\sqrt{5}=5\) गलत है क्योंकि \(5^2=25\) होता है। चरण 2: सही प्रमाण में \(\sqrt{5}\) को परिमेय मानकर विरोधाभास निकाला जाता है। चरण 3: वर्गमूल को अंदर की संख्या के बराबर न मानें।
