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