The integral you're asking to evaluate is:

\[
\int \frac{x^2}{\sqrt[4]{x^3 + 2}} \, dx
\]

To solve this, let's apply a substitution method.

### Step-by-Step Solution:

1. **Substitution**: Let \( u = x^3 + 2 \). Then:
   \[
   du = 3x^2 \, dx \quad \Rightarrow \quad \frac{du}{3} = x^2 \, dx
   \]

2. **Rewrite the integral**: Using this substitution, the integral becomes:
   \[
   \int \frac{x^2}{\sqrt[4]{x^3 + 2}} \, dx = \int \frac{1}{\sqrt[4]{u}} \cdot \frac{du}{3}
   \]
   which simplifies to:
   \[
   \frac{1}{3} \int u^{-\frac{1}{4}} \, du
   \]

3. **Solve the integral**: The integral of \( u^{-\frac{1}{4}} \) is:
   \[
   \frac{1}{3} \cdot \left( \frac{u^{\frac{3}{4}}}{\frac{3}{4}} \right) = \frac{4}{9} u^{\frac{3}{4}}
   \]

4. **Substitute back \( u = x^3 + 2 \)**:
   \[
   \frac{4}{9} (x^3 + 2)^{\frac{3}{4}} + C
   \]

### Final Answer:
\[
\int \frac{x^2}{\sqrt[4]{x^3 + 2}} \, dx = \frac{4}{9} (x^3 + 2)^{\frac{3}{4}} + C
\]
