Question 213272: Write 2lnx + lny - ln(z-3) as a single log expression.
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! 2lnx + lny - ln(z-3)
If you need additional help with logarithms, check out my website by doing a "Bing" search for my last name "Rapalje". Look for "Rapalje Homepage" at the top of the search list, and choose the link on my homepage "Basic, Intermediate and College Algebra: One Step at a Time." Click on "College Algebra", and you will find an entire Chapter, Chapter 4, on Logarithms. My non-traditional explanation should be easier to understand than your textbook!
In addition, I have two videos that are freely available on my website. From my Homepage, click on the link "Rapalje Videos", look for "College Algebra" and then "Logarithms." The videos are a few years old, and the calculator technology is out of date, but this is an explanation that should be easier for you to understand.
