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
Correct Answer

B. (5)

Step 1

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).

Step 2

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).

Step 3

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।
