For an additional explanation of Logarithms, see my own website by doing a "Bing" search for my last name "Rapalje". Look for my website "Rapalje Homepage" near the top of the search list.

Select "College Algebra" and look in "Chapter 4" for "4.01 Definition of Logarithms" This is my own non-traditional explanation that my own students ALL found easier to understand than the one given in traditional textbooks. See also the corresponding section in my "MATH IN LIVING COLOR" pages in which I solved a lot of these types of problems in COLOR!! In addition, I have 2 two-hour videos from my own classes a few years ago that you can see for free on my website. To see the videos, look on my Homepage for "Rapalje Videos in Living Color," and choose "College Algebra".
