How to Convert Between Logarithmic and Exponential Functions You already know that the log and exponential functions are inversely proportional to each other. However, what will you do if some tell you to convert a log function to an exponential one or vice versa? We will discuss this here in detail First, you should be aware of how each function is written. The log function is written in the form of y= logbx, while the same function in the exponential form is written in the form of by = x. Now, to learn conversion from an exponential form to the logarithm form, let us consider an example. 5x = 25 In the above equation, the base is the number on the left-hand side of the above function. In the logarithm function, the base lies with the log function. Let's take the above example and rewrite it as a logarithmic function. x = log525 Similar is the case when you want to convert a log function to an exponential one. This is a series of lessons and worksheets that help students convert between logarithmic and exponential forms of functions.
