Evaluate: `int((x^4-x)^(1//4))/(x^5)\ dx`

Explanation

To evaluate the integral \( I = \int \frac{(x^4 - x)^{1/4}}{x^5} \, dx \), we can follow these steps:

### Step 1: Simplify the Integral
First, we rewrite the integral in a more manageable form:
\[ I = \int \frac{(x^4 - x)^{1/4}}{x^5} \, dx = \int \frac{(x^4(1 - \frac{1}{x^3}))^{1/4}}{x^5} \, dx \]
This can be simplified further by factoring out \( x^4 \):
