यदि \(b\neq3\), तो ((b-3)x^{12}+2x-5-9) की डिग्री क्या होगी?
If \(b\neq3\), what will be the degree of ((b-3)x^{12}+2x-5-9)?
Explanation opens after your attempt
B. (12)
Concept
When \(b\neq3\), the coefficient of \(x^{12}\) is not zero. Therefore the highest power remains (12).
Why this answer is correct
The correct answer is B. (12). When \(b\neq3\), the coefficient of \(x^{12}\) is not zero. Therefore the highest power remains (12).
Exam Tip
\(b\neq3\) होने पर \(x^{12}\) का गुणांक शून्य नहीं है। इसलिए सबसे बड़ी घात (12) रहेगी।
