किस मान पर (\(u^2-81\)x^{13}+(u-9)x-6+5) की डिग्री (0) होगी?
For which value will (\(u^2-81\)x^{13}+(u-9)x-6+5) have degree (0)?
Explanation opens after your attempt
A. (u=9)
Concept
For degree (0), both \(x^{13}\) and \(x^6\) terms must vanish. At (u=9), both coefficients are (0).
Why this answer is correct
The correct answer is A. (u=9). For degree (0), both \(x^{13}\) and \(x^6\) terms must vanish. At (u=9), both coefficients are (0).
Exam Tip
डिग्री (0) के लिए \(x^{13}\) और \(x^6\) दोनों पद हटने चाहिए। (u=9) पर दोनों गुणांक (0) हैं।
