# Chapter 2 - Differentiation - 2.2 Exercises: 9

The derivative is $\frac{1}{5\sqrt[5] {x^4}}$

#### Work Step by Step

To solve this question, it involved a bit of rearrangement and usage of the power rule. The function can be rewritten as $x^{1/5}$. Using the power rule, we get the derivative to be $1/5*x^{-4/5}$ which can be rewritten as $\frac{1}{5\sqrt[5] {x^4}}$.
