Question

FInd the derivative of the image below

The function presented is \( L(x) = \ln(x) + \log_5(x) \).

### Explanation:
- **\(\ln(x)\)**: This represents the natural logarithm of \(x\), which is the logarithm to the base \(e\), where \(e\) is approximately equal to 2.71828.
- **\(\log_5(x)\)**: This term represents the logarithm of \(x\) with base 5.

### Graph/Diagram Explanation:
The expression combines two different types of logarithms. When visualizing such a function on a graph:
- The curve will showcase how both terms contribute to the overall value of \(L(x)\).
- As \(x\) increases, both \(\ln(x)\) and \(\log_5(x)\) increase, but at different rates due to their different bases.
- The graph will typically only be defined for \(x > 0\) since logarithms are not defined for zero or negative values.

This function can be used to demonstrate the effects of different logarithmic bases on the behavior of logarithmic functions.
