### Calculating the Derivative of y with respect to x

**Problem Statement:**
Calculate the derivative of \( y \) with respect to \( x \). Express the derivative in terms of \( x \) and \( y \).

Given the equation:
\[ e^{4xy} = \sin(y^5) \]

**Requirements:**
- Express numbers in exact form.
- Use symbolic notation and fractions where needed.

---

**Solution:**

The incorrect attempt at a solution provided is:

\[ \frac{dy}{dx} = \frac{5y(e^{5xy})}{(4y^3 \cos(y^4) - 5xe^{5xy})} \]

The provided answer is marked as **Incorrect**.

##### Note:
To solve this problem correctly, apply implicit differentiation.

Remember that when differentiating both sides of the equation with respect to \( x \), you'll need to use the chain rule and product rule accordingly. 

For \( e^{4xy} \):
\[ \frac{d(e^{4xy})}{dx} = e^{4xy} \cdot \frac{d(4xy)}{dx} = e^{4xy} \cdot (4y + 4x \frac{dy}{dx}) \]

For \( \sin(y^5) \):
\[ \frac{d(\sin(y^5))}{dx} = \cos(y^5) \cdot \frac{d(y^5)}{dx} = \cos(y^5) \cdot 5y^4 \cdot \frac{dy}{dx} \]

Setting these equal gives:
\[ e^{4xy} \cdot (4y + 4x \frac{dy}{dx}) = \cos(y^5) \cdot 5y^4 \cdot \frac{dy}{dx} \]

Isolating \(\frac{dy}{dx}\) will lead to the correct solution.
