or

Reject the negative answer, since it gives a log of a negative number, which is NOT allowed.

You will have to calculate the decimal approximation yourself! I'm on vacation for a few days, and I didn't bring my calculator!!

For additional help with the LOGARITHMS, please see my own website. Just click on my tutor name "rapaljer" anywhere in algebra.com. A link there will connect you to my website. On my Homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time." Choose "College Algebra", and look in "Chapter 4" for the entire chapter on "Logarithms". Also see solutions to these kinds of problems on my "MATH IN LIVING COLOR" pages that corrspond to these pages. Most people tell me that my explanations are a lot easier to understand than their expensive textbooks--and MINE ARE ALL FREE!!! Imagine that!!

In addition, I have FREE videos from my classes before I retired of me teaching LOGARITHMS. To see my videos, look for "Rapalje Videos in Living Color." Again, choose "College Algebra," and look for the appropriate topic.

If you like my explanations, all I ask is that you recommend them to friends and family!!
