Alissa is currently a teacher in the San Francisco Bay Area and Brightstorm users love her clear, concise explanations of tough concepts
Here we look at a variety of examples for how to move back and forth from log to exponential form. In order to do this successfully, you MUST know the definition of logs that tells you which parts of an exponential relationship go where in log form. Logs and exponential functions are inverses. "ln" means the natural log, or base "e," and if there is no base noted with the log, then there is an implied base 10. These problems address the most important foundational skills that you'll need for working with logarithmic and exponential functions.
