It appears that you have uploaded an image with a problem asking to calculate \(\frac{dy}{dx}\) for two different equations. Here's what I interpret from the image:

1. **Problem (a):**  
   \(\frac{dy}{dx}\) if \(x^3 - 4y^3 = 5 - 3x^2\).

2. **Problem (b):**  
   \(\frac{dy}{dx}\) if \(\frac{x^3}{y^2} = 5x^2 + 6y^3\).

Let me go ahead and solve each one.

### Problem (a) Solution:

The given equation is:
\[
x^3 - 4y^3 = 5 - 3x^2
\]

To find \(\frac{dy}{dx}\), we will differentiate both sides implicitly.

1. Differentiate the left-hand side:
   \[
   \frac{d}{dx}(x^3 - 4y^3) = 3x^2 - 12y^2 \frac{dy}{dx}
   \]
   (Here, we used the chain rule for \(-4y^3\)).

2. Differentiate the right-hand side:
   \[
   \frac{d}{dx}(5 - 3x^2) = -6x
   \]

Now, equate the derivatives:
\[
3x^2 - 12y^2 \frac{dy}{dx} = -6x
\]

Solve for \(\frac{dy}{dx}\):
\[
-12y^2 \frac{dy}{dx} = -6x - 3x^2
\]
\[
\frac{dy}{dx} = \frac{-6x - 3x^2}{-12y^2}
\]
\[
\frac{dy}{dx} = \frac{x(6 + 3x)}{12y^2}
\]

So, the solution for part (a) is:
\[
\frac{dy}{dx} = \frac{x(6 + 3x)}{12y^2}
\]

### Problem (b) Solution:

The given equation is:
\[
\frac{x^3}{y^2} = 5x^2 + 6y^3
\]

Again, we will differentiate both sides implicitly.

1. Differentiate the left-hand side:
   \[
   \frac{d}{dx}\left(\frac{x^3}{y^2}\right) = \frac{3x^2 y^2 - x^3 (2y \frac{dy}{dx})}{y^4} = \frac{3x^2 y^2 - 2x^3 y \frac{dy}{dx}}{y^4}
   \]

2. Differentiate the right-hand side:
   \[
   \frac{d}{dx}(5x^2 + 6y^3) = 10x + 18y^2 \frac{dy}{dx}
   \]

Now, equate the derivatives:
\[
\frac{3x^2 y^2 - 2x^3 y \frac{dy}{dx}}{y^4} = 10x + 18y^2 \frac{dy}{dx}
\]

To simplify this equation, multiply both sides by \(y^4\):
\[
3x^2 y^2 - 2x^3 y \frac{dy}{dx} = y^4 (10x + 18y^2 \frac{dy}{dx})
\]

At this point, you can solve for \(\frac{dy}{dx}\) by isolating the terms involving it and factorizing.
