वर्गमूल सर्पिल में यदि \(\sqrt{n}\) के बाद बना कर्ण पूर्ण संख्या (20) है, तो (n) का मान क्या था?
In a square root spiral, if the hypotenuse formed after \(\sqrt{n}\) is the whole number (20), what was the value of (n)?
Explanation opens after your attempt
A. (399)
Concept
The new hypotenuse is \(20=\sqrt{400}\). Therefore (n+1=400), so (n=399).
Why this answer is correct
The correct answer is A. (399). The new hypotenuse is \(20=\sqrt{400}\). Therefore (n+1=400), so (n=399).
Exam Tip
नया कर्ण \(20=\sqrt{400}\) है। इसलिए (n+1=400), अतः (n=399)।
