The given function is:

\[
y = \frac{e^{x^4}}{\sqrt{2 - x^3}}.
\]

We need to differentiate \( y \) with respect to \( x \) to find \( \frac{dy}{dx} \). We'll use both the quotient rule and chain rule to handle this differentiation.

### Step 1: Apply the quotient rule
The quotient rule states:

\[
\frac{d}{dx} \left( \frac{f(x)}{g(x)} \right) = \frac{f'(x) g(x) - f(x) g'(x)}{[g(x)]^2},
\]

where \( f(x) = e^{x^4} \) and \( g(x) = \sqrt{2 - x^3} \).

### Step 2: Differentiate the numerator \( f(x) = e^{x^4} \)

Using the chain rule, the derivative of \( e^{x^4} \) is:

\[
f'(x) = \frac{d}{dx} e^{x^4} = e^{x^4} \cdot \frac{d}{dx}(x^4) = e^{x^4} \cdot 4x^3.
\]

### Step 3: Differentiate the denominator \( g(x) = \sqrt{2 - x^3} \)

First, express \( g(x) = (2 - x^3)^{1/2} \). Using the chain rule, we differentiate as follows:

\[
g'(x) = \frac{1}{2} (2 - x^3)^{-1/2} \cdot \frac{d}{dx} (2 - x^3) = \frac{1}{2} (2 - x^3)^{-1/2} \cdot (-3x^2).
\]

Thus:

\[
g'(x) = -\frac{3x^2}{2 \sqrt{2 - x^3}}.
\]

### Step 4: Apply the quotient rule

Now substitute into the quotient rule formula:

\[
\frac{dy}{dx} = \frac{e^{x^4} \cdot 4x^3 \cdot \sqrt{2 - x^3} - e^{x^4} \cdot \left( -\frac{3x^2}{2 \sqrt{2 - x^3}} \right)}{(2 - x^3)}.
\]

### Step 5: Simplify the result

The expression becomes:

\[
\frac{dy}{dx} = \frac{e^{x^4}}{(2 - x^3)} \left( 4x^3 \sqrt{2 - x^3} + \frac{3x^2}{2 \sqrt{2 - x^3}} \right).
\]

This is the derivative of \( y \) with respect to \( x \).
