यदि (e=5), तो ((e-5)x^{14}+(e+3)x^{12}+9x-5-4) की डिग्री क्या है?
If (e=5), what is the degree of ((e-5)x^{14}+(e+3)x^{12}+9x-5-4)?
Explanation opens after your attempt
B. (12)
Concept
At (e=5), the \(x^{14}\) term vanishes but the coefficient of \(x^{12}\) remains (8). Therefore the degree is (12).
Why this answer is correct
The correct answer is B. (12). At (e=5), the \(x^{14}\) term vanishes but the coefficient of \(x^{12}\) remains (8). Therefore the degree is (12).
Exam Tip
(e=5) पर \(x^{14}\) पद हटता है लेकिन \(x^{12}\) का गुणांक (8) रहता है। इसलिए डिग्री (12) है।
