### Evaluating a Triple Integral by Hand

In this exercise, we are required to evaluate the following triple integral by hand:

\[ \int_{z=1}^{9} \int_{y=2}^{4} \int_{x=-1}^{2} \frac{x^4 \sqrt{z}}{y^3} \, dx \, dy \, dz \]

#### Steps to Solve:

1. **Set up the Integral:** 
   - The integral is set up in the standard order of integration from inner to outer: \(dx\), \(dy\), \(dz\).

2. **Integrate with respect to \(x\):**
   - Evaluate the innermost integral (with respect to \(x\)) while treating \(y\) and \(z\) as constants:
   
   \[
   \int_{x=-1}^{2} \frac{x^4 \sqrt{z}}{y^3} \, dx
   \]

3. **Integrate with respect to \(y\):**
   - After simplifying the result from \(x\) integration, integrate with respect to \(y\):
   
   \[
   \int_{y=2}^{4} \left( \text{Result from the } x \text{-integration} \right) \, dy
   \]

4. **Integrate with respect to \(z\):**
   - Finally, integrate with respect to \(z\) using the result from the \(y\) integration:
   
   \[
   \int_{z=1}^{9} \left( \text{Result from the } y \text{-integration} \right) \, dz
   \]

By following these steps in sequence, one can evaluate the given triple integral manually.
