Explanation opens after your attempt
Correct Answer
A. (m=400)
Concept
\(400=20^2\) is a perfect square so \(\sqrt{400}\) is rational. The other options are not perfect squares.
Why this answer is correct
The correct answer is A. (m=400). \(400=20^2\) is a perfect square so \(\sqrt{400}\) is rational. The other options are not perfect squares.
Exam Tip
\(400=20^2\) पूर्ण वर्ग है इसलिए \(\sqrt{400}\) परिमेय है। बाकी विकल्प पूर्ण वर्ग नहीं हैं।
