This math topic focuses on finding the inverse functions of exponential and logarithmic functions. The problems require converting given exponential or logarithmic functions into their inverse forms. Each example features a function, such as a logarithmic function with a base or a natural logarithm (`ln`), and the task is to determine the correct inverse function from multiple choices. This is a fundamental exercise in understanding how functions and their inverses work, particularly within the realms of exponential and logarithmic operations.
