यदि (e=-1), तो ((e+1)x^{11}+(e-2)x-9+5x-3-6) की डिग्री क्या है?
If (e=-1), what is the degree of ((e+1)x^{11}+(e-2)x-9+5x-3-6)?
Explanation opens after your attempt
B. (9)
Concept
At (e=-1), the \(x^{11}\) term vanishes but the coefficient of \(x^9\) remains (-3). Therefore the degree is (9).
Why this answer is correct
The correct answer is B. (9). At (e=-1), the \(x^{11}\) term vanishes but the coefficient of \(x^9\) remains (-3). Therefore the degree is (9).
Exam Tip
(e=-1) पर \(x^{11}\) पद हटता है लेकिन \(x^9\) का गुणांक (-3) रहता है। इसलिए डिग्री (9) है।
