# The term independent of $x$ in the expansion $\bigg(\large\frac{x+1}{x^{\large\frac{2}{3}}-x^{\large\frac{1}{3}}+1}-\frac{x-1}{x-\sqrt x}\bigg)^{10}$ is ?

$\begin{array}{1 1} 4 \\ 120 \\ 210 \\ 0 \end{array}$

Can you answer this question?

$x+1=(x^{\frac{1}{3}})^3+1^3$$=(x^{\frac{1}{3}}+1)$$(x^{\frac{2}{3}}-x^{\frac{1}{3}}+1)$
