To identify the items in your list as expressions or equations:

1. **2x^3 - 4x^2**: This is an **expression**. It does not contain an equality sign ("=").

2. **x = 3x^2 - 4**: This is an **equation**. It contains an equality sign.

3. **5^x = 25**: This is an **equation** as well, due to the presence of the equality sign.

4. **3x + 2pi**: This is an **expression**. It does not have an equality sign.

To summarize:
- **Expressions**: 2x^3 - 4x^2, 3x + 2pi
- **Equations**: x = 3x^2 - 4, 5^x = 25
