सरल करने के बाद (x-6\(x^4-2\)-x^{10}+3x-7-9) की डिग्री क्या है?

Correct Answer

B. (7)

Step 1

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).

Step 2

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).

Step 3

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।
