The image shows the integral:

$\int_8^{27} \frac{dx}{x - x^{1/3}} = \frac{3}{2} \ln \frac{8}{3}$

To solve this, let’s break down the approach:

Step 1: Simplify the Integrand

Rewrite $x - x^{1/3}$ by setting $x = t^3$, which implies $dx = 3t^2 \, dt$. Then:

1. Substitute $x = t^3$ into the integral.
2. Solve and simplify the integral using the limits transformed by this substitution.
3. Confirm that it matches $\frac{3}{2} \ln \frac{8}{3}$ as shown.
