*Rewrite in exponential form *Base = 10 and exponent = 3

Remember that when there is no base written on a log, that means it
is the common log, or log base 10. If you need a review on common
logs feel free to go to Tutorial

Since -2 would create a negative number inside
both logs in this problem and we CANNOT take the log of a negative number,
we will have to throw out x = -2 as one of
our solutions.

The equation that we had to solve in step 3 had a rational expression
in it. If you need a review on solving equations with rational expressions

*Rewrite in exponential form *Base = e and
exponent = 1

Remember that when you have ln, that means it is the natural log, or
log base e. If you need a review on natural
logs feel free to go to Tutorial
