सरल करने के बाद (x-4\(x^5-3x\)-x-9+6x-6-2) की डिग्री क्या है?
After simplifying (x-4\(x^5-3x\)-x-9+6x-6-2), what is the degree?
Explanation opens after your attempt
B. (6)
Concept
On expanding, we get \(x^9-3x^5-x^9+6x^6-2\). The \(x^9\) term cancels and the highest power left is (6).
Why this answer is correct
The correct answer is B. (6). On expanding, we get \(x^9-3x^5-x^9+6x^6-2\). The \(x^9\) term cancels and the highest power left is (6).
Exam Tip
फैलाने पर \(x^9-3x^5-x^9+6x^6-2\) मिलता है। \(x^9\) कटता है और सबसे बड़ी घात (6) रहती है।
