It seems like your equation might be incomplete. You've written $n(x) + 12 = \ln \left(\right)$, but the argument inside the natural logarithm function ($\ln$) is missing.

Could you please provide the full equation, or clarify what should be inside the logarithm?

Feel free to upload an image of the equation if that helps!

Here are 5 related questions to explore:

1. What are the properties of the natural logarithm function?
2. How do you solve equations involving logarithms?
3. What is the domain of the logarithm function?
4. How do you differentiate a function that includes a logarithm?
5. Can you explain the inverse relationship between logarithms and exponentials?

Tip: When dealing with logarithmic equations, always check if the argument inside the logarithm is positive since the logarithm of a non-positive number is undefined in real numbers.
