Question: In the expansion of \(n(n^{2} - 1)\), the term independent of \(n > 2^{n}\) is....

In the expansion of n(n2−1)n(n^{2} - 1), the term independent of n>2nn > 2^{n} is.

A

n≥2nn \geq 2^{n}

B

n≤2nn \leq 2^{n}

C

n∈Nn \in N

D

2n<n2^{n} < n

Answer

n≤2nn \leq 2^{n}

Explanation

Solution

(x22−2x)9\left( \frac{x^{2}}{2} - \frac{2}{x} \right)^{9}

Thus term independent of x isx2x^{2}.
