यदि (p(x)=(a-4)x^{10}+(a+2)x-6+3x-2-5) की डिग्री (6) है, तो (a) का सही मान कौन सा है?
If the degree of (p(x)=(a-4)x^{10}+(a+2)x-6+3x-2-5) is (6), which value of (a) is correct?
Explanation opens after your attempt
A. (a=4)
Concept
For degree (6), the \(x^{10}\) term must vanish and the \(x^6\) term must remain. This condition holds at (a=4).
Why this answer is correct
The correct answer is A. (a=4). For degree (6), the \(x^{10}\) term must vanish and the \(x^6\) term must remain. This condition holds at (a=4).
Exam Tip
डिग्री (6) के लिए \(x^{10}\) पद हटना चाहिए और \(x^6\) पद बचना चाहिए। (a=4) पर यह शर्त पूरी होती है।
