On Thursday/Friday, students learned how to apply logarithms to solve basic exponential equations in the form ab^x+c=d. They did pretty well with it, although, as expected, when I threw in a power equation at the end (like ax^b+c=d) everyone took the log of both sides and then got stuck. Analysis is something my students are notoriously poor at, and teaching students how to analyze is notoriously difficult. In the next lesson, we will review roots and logs, and the focus will be on how to tell when you should use one or the other.
