यदि \(r\neq0\), तो \(rx^7+3x^2-10\) की डिग्री क्या होगी?
If \(r\neq0\), what will be the degree of \(rx^7+3x^2-10\)?
Explanation opens after your attempt
C. (7)
Concept
Since \(r\neq0\), the \(x^7\) term remains present. Therefore the highest power is (7).
Why this answer is correct
The correct answer is C. (7). Since \(r\neq0\), the \(x^7\) term remains present. Therefore the highest power is (7).
Exam Tip
\(r\neq0\) होने से \(x^7\) पद मौजूद रहेगा। इसलिए सबसे बड़ी घात (7) है।
