For degree (5), the \(x^8\) term must vanish and the \(x^5\) term must remain. This condition holds at (d=8).
Why this answer is correct
The correct answer is B. (d=8). For degree (5), the \(x^8\) term must vanish and the \(x^5\) term must remain. This condition holds at (d=8).
Exam Tip
डिग्री (5) के लिए \(x^8\) पद हटना चाहिए और \(x^5\) पद बचना चाहिए। (d=8) पर यह शर्त पूरी होती है।
