व्यंजक ((a-2)x-5+4x-3-1) की डिग्री (5) कब होगी?
When will the degree of ((a-2)x-5+4x-3-1) be (5)?
Explanation opens after your attempt
D. जब \(a\neq2\)When \(a\neq2\)
Concept
The degree will be (5) only when the coefficient of \(x^5\) is not zero. Therefore \(a-2\neq0\).
Why this answer is correct
The correct answer is D. जब \(a\neq2\) / When \(a\neq2\). The degree will be (5) only when the coefficient of \(x^5\) is not zero. Therefore \(a-2\neq0\).
Exam Tip
डिग्री (5) तभी होगी जब \(x^5\) का गुणांक शून्य न हो। इसलिए \(a-2\neq0\) होना चाहिए।
