कौन सा विकल्प \(\sqrt{5}\) के प्रमाण में (q) के (5) से विभाज्य होने तक सही रास्ता दिखाता है?
Which option shows the correct path to prove (q) divisible by (5) in the proof of \(\sqrt{5}\)?
Explanation opens after your attempt
Correct Answer
A. \(p^2=5q^2\), (p=5k), \(25k^2=5q^2\), \(q^2=5k^2\)
Step 1
Concept
\(p^2=5q^2\) से (p) (5) से विभाज्य है, इसलिए (p=5k)। / From \(p^2=5q^2\), (p) is divisible by (5), so (p=5k).
Step 2
Why this answer is correct
रखने पर \(25k^2=5q^2\) और फिर \(q^2=5k^2\) मिलता है। / Substitution gives \(25k^2=5q^2\), then \(q^2=5k^2\).
Step 3
Exam Tip
इससे (q) भी (5) से विभाज्य सिद्ध होता है। / This proves (q) is also divisible by (5).
