Start as how you start to any derivative, difference quotient.

as I interpret
$$(\frac{x}{x^2}+1)^3$$

start with the chain rule with power rule , then quotient and difference rule .

Start by clarifying your expression.
[itex](\frac{x}{x^2+1})^3[/itex] or [itex](\frac{1}{x}+1)^3[/itex]?

In the future, post questions like this in the Homework & Coursework section (under Calculus), not here in the technical sections. When you post a question in the Homework section, a template appears into which you enter the problem description, any formulas or equations, and what you have tried.
