यदि (q(x)=(k-4)2x-8+(k-4)x-5+3x) और (k=4), तो (q(x)) की डिग्री क्या है?
If (q(x)=(k-4)2x-8+(k-4)x-5+3x) and (k=4), what is the degree of (q(x))?
Explanation opens after your attempt
C. (1)
Concept
At (k=4), both \(x^8\) and \(x^5\) terms vanish. The remaining (3x) has degree (1).
Why this answer is correct
The correct answer is C. (1). At (k=4), both \(x^8\) and \(x^5\) terms vanish. The remaining (3x) has degree (1).
Exam Tip
(k=4) पर \(x^8\) और \(x^5\) दोनों पद हट जाते हैं। बचा (3x) है जिसकी डिग्री (1) है।
