Obtain the differential coefficient of the following:
(i) `e^(nx)` (ii) `a^(nx)`

Explanation

To find the differential coefficients of the given functions, we will differentiate each function step by step.

### Part (i): Differentiate \( e^{nx} \)

1. **Identify the function**: Let \( y = e^{nx} \).
2. **Apply the chain rule**: The derivative of \( e^u \) with respect to \( x \) is \( e^u \cdot \frac{du}{dx} \), where \( u = nx \).
3. **Differentiate \( u = nx \)**:
- The derivative of \( u \) with respect to \( x \) is \( \frac{du}{dx} = n \) (since \( n \) is a constant).
