Correct Answer

B. (11)

Step 1

Concept

Multiplication gives \(x^{15}+3x^{11}-4x^7\), and \(x^{15}\) cancels. The remaining highest power is (11).

Step 2

Why this answer is correct

The correct answer is B. (11). Multiplication gives \(x^{15}+3x^{11}-4x^7\), and \(x^{15}\) cancels. The remaining highest power is (11).

Step 3

Exam Tip

गुणन से \(x^{15}+3x^{11}-4x^7\) मिलता है और \(x^{15}\) कटता है। बची सबसे बड़ी घात (11) है।
