I have additional explanation in both written and video format with examples solved in LIVING COLOR on my own website. Please go to "www2.seminolestate.edu/rrapalje". Look for the links on my Homepage "Basic, Intermediate, and College Algebra: One Step at a Time" and also "MATH IN LIVING COLOR", and look under "College Algebra" (Chapter 4).
I also have a complete video from my own teaching in class before I retired a few years ago on Logarithms. To see the video, look for "Rapalje Videos in Living Color", and see College Algebra for the topic of Logarithms.
I think you will find the explanations, both written and video, much easier to understand than traditional textbooks. Best of all, it's all FREE--even the VIDEO!!
