Obtian `(dy)/(dx)` for the following :
(i) `(3-4x^(2))^(2)`
(ii) `sqrt((3+x^(2)))`

Explanation

To find the derivative \( \frac{dy}{dx} \) for the given functions, we will apply the chain rule and basic differentiation rules. Let's solve each part step by step.

### Part (i): \( y = (3 - 4x^2)^2 \)

1. **Identify the outer and inner functions**:
- Outer function: \( u^2 \) where \( u = 3 - 4x^2 \)
- Inner function: \( u = 3 - 4x^2 \)
