$$\left(3 \sqrt[3]{x} - \frac{1}{x}\right) + 1$$

3*x^(1/3) - 1/x + 1

Detail solution

Differentiate $\left(3 \sqrt[3]{x} - \frac{1}{x}\right) + 1$ term by term:
1. Differentiate $3 \sqrt[3]{x} - \frac{1}{x}$ term by term:
  1. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $\sqrt[3]{x}$ goes to $\frac{1}{3 x^{\frac{2}{3}}}$
    So, the result is: $\frac{1}{x^{\frac{2}{3}}}$
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $\frac{1}{x}$ goes to $- \frac{1}{x^{2}}$
    So, the result is: $\frac{1}{x^{2}}$
  The result is: $\frac{1}{x^{2}} + \frac{1}{x^{\frac{2}{3}}}$
2. The derivative of the constant $1$ is zero.
The result is: $\frac{1}{x^{2}} + \frac{1}{x^{\frac{2}{3}}}$

The answer is:

$\frac{1}{x^{2}} + \frac{1}{x^{\frac{2}{3}}}$
