सरल करने के बाद (7x-9\(x^2-1\)-7x^{11}+6x-8) की डिग्री क्या है?
After simplifying (7x-9\(x^2-1\)-7x^{11}+6x-8), what is the degree?
Explanation opens after your attempt
B. (9)
Concept
(7x-9\(x^2-1\)=7x^{11}-7x-9), and \(7x^{11}\) cancels. The remaining highest power is (9).
Why this answer is correct
The correct answer is B. (9). (7x-9\(x^2-1\)=7x^{11}-7x-9), and \(7x^{11}\) cancels. The remaining highest power is (9).
Exam Tip
(7x-9\(x^2-1\)=7x^{11}-7x-9) और \(7x^{11}\) कटता है। बची सबसे बड़ी घात (9) है।
