किस मान पर (\(s^2-121\)x^{13}+(s+11)x-9+7) की डिग्री (0) होगी?
For which value will (\(s^2-121\)x^{13}+(s+11)x-9+7) have degree (0)?
Explanation opens after your attempt
B. (s=-11)
Concept
For degree (0), both \(x^{13}\) and \(x^9\) terms must vanish. At (s=-11), both coefficients become (0).
Why this answer is correct
The correct answer is B. (s=-11). For degree (0), both \(x^{13}\) and \(x^9\) terms must vanish. At (s=-11), both coefficients become (0).
Exam Tip
डिग्री (0) के लिए \(x^{13}\) और \(x^9\) दोनों पद हटने चाहिए। (s=-11) पर दोनों गुणांक (0) हो जाते हैं।
