किस मान पर (\(u^2-49\)x^{10}+(u-7)x-4+5) की डिग्री (0) होगी?
For which value will (\(u^2-49\)x^{10}+(u-7)x-4+5) have degree (0)?
Explanation opens after your attempt
A. (u=7)
Concept
For degree (0), both \(x^{10}\) and \(x^4\) terms must vanish. At (u=7), both coefficients are (0).
Why this answer is correct
The correct answer is A. (u=7). For degree (0), both \(x^{10}\) and \(x^4\) terms must vanish. At (u=7), both coefficients are (0).
Exam Tip
डिग्री (0) के लिए \(x^{10}\) और \(x^4\) दोनों पद हटने चाहिए। (u=7) पर दोनों गुणांक (0) हैं।
