यदि (e=-4), तो ((e+4)x^{13}+(e-1)x^{11}+8x-4-2) की डिग्री क्या है?
If (e=-4), what is the degree of ((e+4)x^{13}+(e-1)x^{11}+8x-4-2)?
Explanation opens after your attempt
B. (11)
Concept
At (e=-4), the \(x^{13}\) term vanishes but the coefficient of \(x^{11}\) remains (-5). Therefore the degree is (11).
Why this answer is correct
The correct answer is B. (11). At (e=-4), the \(x^{13}\) term vanishes but the coefficient of \(x^{11}\) remains (-5). Therefore the degree is (11).
Exam Tip
(e=-4) पर \(x^{13}\) पद हटता है लेकिन \(x^{11}\) का गुणांक (-5) रहता है। इसलिए डिग्री (11) है।
