यदि \(b\neq4\), तो ((b-4)x^{13}+6x-7-2) की डिग्री क्या होगी?
If \(b\neq4\), what will be the degree of ((b-4)x^{13}+6x-7-2)?
Explanation opens after your attempt
C. (13)
Concept
When \(b\neq4\), the coefficient of \(x^{13}\) is not zero. Therefore the highest power remains (13).
Why this answer is correct
The correct answer is C. (13). When \(b\neq4\), the coefficient of \(x^{13}\) is not zero. Therefore the highest power remains (13).
Exam Tip
\(b\neq4\) होने पर \(x^{13}\) का गुणांक शून्य नहीं है। इसलिए सबसे बड़ी घात (13) रहेगी।
