यदि \(a\neq1\), तो ((a-1)x^{10}+7x-4-8) की डिग्री क्या होगी?
If \(a\neq1\), what will be the degree of ((a-1)x^{10}+7x-4-8)?
Explanation opens after your attempt
C. (10)
Concept
When \(a\neq1\), the coefficient of \(x^{10}\) is not zero. Therefore the highest power remains (10).
Why this answer is correct
The correct answer is C. (10). When \(a\neq1\), the coefficient of \(x^{10}\) is not zero. Therefore the highest power remains (10).
Exam Tip
\(a\neq1\) होने पर \(x^{10}\) का गुणांक शून्य नहीं है। इसलिए सबसे बड़ी घात (10) रहेगी।
