यदि (e=3), तो ((e-3)x^{12}+(e+2)x^{10}+6x-4-7) की डिग्री क्या है?
If (e=3), what is the degree of ((e-3)x^{12}+(e+2)x^{10}+6x-4-7)?
Explanation opens after your attempt
B. (10)
Concept
At (e=3), the \(x^{12}\) term vanishes but the coefficient of \(x^{10}\) remains (5). Therefore the degree is (10).
Why this answer is correct
The correct answer is B. (10). At (e=3), the \(x^{12}\) term vanishes but the coefficient of \(x^{10}\) remains (5). Therefore the degree is (10).
Exam Tip
(e=3) पर \(x^{12}\) पद हटता है लेकिन \(x^{10}\) का गुणांक (5) रहता है। इसलिए डिग्री (10) है।
