सरल करने के बाद (2x-4\(x^3-1\)-2x-7+9x-5) की डिग्री क्या है?
After simplifying (2x-4\(x^3-1\)-2x-7+9x-5), what is the degree?
Explanation opens after your attempt
B. (5)
Concept
(2x-4\(x^3-1\)=2x-7-2x-4), and \(2x^7\) cancels. The remaining \(9x^5-2x^4\) has degree (5).
Why this answer is correct
The correct answer is B. (5). (2x-4\(x^3-1\)=2x-7-2x-4), and \(2x^7\) cancels. The remaining \(9x^5-2x^4\) has degree (5).
Exam Tip
(2x-4\(x^3-1\)=2x-7-2x-4) और \(2x^7\) कटता है। बचा \(9x^5-2x^4\) है जिसकी डिग्री (5) है।
