सरल करने के बाद (x-6\(x^4-2\)-x^{10}+3x-7-9) की डिग्री क्या है?
After simplifying (x-6\(x^4-2\)-x^{10}+3x-7-9), what is the degree?
Explanation opens after your attempt
B. (7)
Concept
On expanding, we get \(x^{10}-2x^6-x^{10}+3x^7-9\). The \(x^{10}\) term cancels and the highest power left is (7).
Why this answer is correct
The correct answer is B. (7). On expanding, we get \(x^{10}-2x^6-x^{10}+3x^7-9\). The \(x^{10}\) term cancels and the highest power left is (7).
Exam Tip
फैलाने पर \(x^{10}-2x^6-x^{10}+3x^7-9\) मिलता है। \(x^{10}\) कटता है और सबसे बड़ी घात (7) रहती है।
