The image you uploaded contains five problems involving differentiation. Here's a breakdown of each problem along with their instructions:

1. $y = (x^3 - 2x)^2$
   Task: Find $y''$ (second derivative).

2. $y = \frac{x}{x+1}$
   Task: Find $y''$.

3. $y = \sqrt[3]{(1 + 2x)^2}$
   Task: Find $y'$ (first derivative) and $y''$ (second derivative).

4. $y = \sqrt{\frac{x^3}{1 - x^2}}$
   Task: Find $y'$ and $y''$.

5. $y = (x + 2)(2 - 1)^3$
   Task: Find $\frac{dy}{dx}$ and $\frac{d^2y}{dx^2}$.

Let me know which problem you'd like me to solve first or if you'd like me to walk you through the solutions in detail!
