I have some more problems just like this, many with solutions IN COLOR, on my own website. Click on my tutor name "rapaljer" anywhere in algebra.com. From my homepage, click on "Basic, Intermediate, and College Algebra: One Step at a Time." Choose "College Algebra", "Chapter 4 Logarithms", "Section 4.04 (Exponential and Logarithmic Equations)".
FREE videos are also available from my Homepage. Look for "Rapalje Videos in Living Color," and look in College Algebra for the videos on Logarithms.
I have many other topics from Basic, Intermediate, and College Algebra that are explained in detail, with many of these topics explained on video as well. Everything on the website is FREE.
