Example 1 Prompt: Evaluate log 7 14 Solution: Using the change of base formula in one step in the calculator, you can see that we get.
![]() Antilogarithms are the inverse of logarithms. In this lesson, well learn how to use the logarithm and antilogarithm functions on a scientific calculator to solve problems. What Is Antilog On A Calculator Zip It ThisHow do you undo a bag or jacket that has been zipped You unzip it This is similar to how logarithms and antilogarithms work. A logarithm, or log, is a mathematical process where you raise the logarithms base (usually 10) to a specific number resulting in some value. An antilogarithm (antilog) is the unzipping of the log function. We raise the base to the value we just determined resulting in the original number we took the log of. Lets look at the expressions that show how log and antilog are inverses of each other. ![]() This is the same key you press for antilog, but you must press the SHIFT or 2ND key first when doing antilog. The difference between the two types is the order you have to press the keys. When the calculator is cleared of any numbers and you press the LOG key, one of two things will happen. If you see the error message, your calculator requires you to enter the value first before pressing the LOG key. Example 1 Prompt: Determine the log of 41230 Solution: If the base of the log is not given we can assume it is 10. ![]() It is log base e, which is Eulers number whose value is 2.7182818. It is commonly rounded to 2.72. The log function with base e is called natural log, which is abbreviated ln. Example 1 Prompt: What is the natural log of 5.22 Solution: Press the LN key followed 5.22 and then the ENTER key. This gives 1.652. Now, lets determine the anti-natural log of this answer. Example 2 Prompt: Determine the anti-natural log of 1.652 Solution: We press the 2ND key, followed by the LN key. This gives 5.217. It isnt exactly 5.22 because we rounded the previous answer. No More Base 10 What if the base isnt 10 but some other value For example, log 7 14. Some calculators have a way to change the base of the log function. Lets look at how to do a change of base log problem if your calculator doesnt have the ability to change the base of the log function. To do this we use the change of base formula, which as you can see, is.
