यदि (w=3), तो ((w-3)x-8+(w+1)x-5-2x+6) की डिग्री क्या होगी?
If (w=3), what will be the degree of ((w-3)x-8+(w+1)x-5-2x+6)?
Explanation opens after your attempt
B. (5)
Concept
Putting (w=3) makes the coefficient of \(x^8\) equal to (0) and the coefficient of \(x^5\) equal to (4). So the highest power is (5).
Why this answer is correct
The correct answer is B. (5). Putting (w=3) makes the coefficient of \(x^8\) equal to (0) and the coefficient of \(x^5\) equal to (4). So the highest power is (5).
Exam Tip
(w=3) रखने पर \(x^8\) का गुणांक (0) और \(x^5\) का गुणांक (4) होता है। इसलिए सबसे बड़ी घात (5) है।
