Problems using the function double log (double __x) of the library <math.h>

I am doing a project and I need to use the logarithmic functions.

The problem is that I cannot find examples of how to use the <math.h> library, so I need someone to explain to me how to use these functions and to be able to do addition, subtraction, multiplication and division with them.

Please, if you can give an example it would be of great help. :slight_smile: :slight_smile: :slight_smile: ;D ;D ;D
