सरल करने के बाद (x-4\(x^3+2\)-x-7+6x-5-8) की डिग्री क्या है?
After simplifying (x-4\(x^3+2\)-x-7+6x-5-8), what is the degree?
Explanation opens after your attempt
B. (5)
Concept
(x-4\(x^3+2\)=x-7+2x-4), and \(x^7\) cancels. The remaining \(6x^5+2x^4-8\) has degree (5).
Why this answer is correct
The correct answer is B. (5). (x-4\(x^3+2\)=x-7+2x-4), and \(x^7\) cancels. The remaining \(6x^5+2x^4-8\) has degree (5).
Exam Tip
(x-4\(x^3+2\)=x-7+2x-4) और \(x^7\) कट जाता है। बचा \(6x^5+2x^4-8\) है जिसकी डिग्री (5) है।
