Correct Answer

B. (5)

Step 1

Concept

On expanding, we get \(2x^8-2x^5-2x^8+7x^4\). The \(x^8\) term cancels and the highest power left is (5).

Step 2

Why this answer is correct

The correct answer is B. (5). On expanding, we get \(2x^8-2x^5-2x^8+7x^4\). The \(x^8\) term cancels and the highest power left is (5).

Step 3

Exam Tip

फैलाने पर \(2x^8-2x^5-2x^8+7x^4\) मिलता है। \(x^8\) कटता है और सबसे बड़ी घात (5) रहती है।
