Which option is a wrong statement in the proof of \(\sqrt{5}\)?
Explanation opens after your attempt
Correct Answer
A. \(\sqrt{5}=5\)
Step 1
Concept
\(\sqrt{5}=5\) is wrong because \(5^2=25\).
Step 2
Why this answer is correct
In the correct proof, \(\sqrt{5}\) is assumed rational and a contradiction is obtained.
Step 3
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 मूल संख्या के बराबर न मानें।
