सरल करने के बाद (x-5\(x^4-3\)-x-9+4x-7-2) की डिग्री क्या है?
After simplifying (x-5\(x^4-3\)-x-9+4x-7-2), what is the degree?
Explanation opens after your attempt
B. (7)
Concept
(x-5\(x^4-3\)=x-9-3x-5), and \(x^9\) cancels. The remaining highest power is (7).
Why this answer is correct
The correct answer is B. (7). (x-5\(x^4-3\)=x-9-3x-5), and \(x^9\) cancels. The remaining highest power is (7).
Exam Tip
(x-5\(x^4-3\)=x-9-3x-5) होता है और \(x^9\) कट जाता है। बची सबसे बड़ी घात (7) है।
