The main thing to remember is: LOGS ARE EXPONENTS
The other main thing is:
You have to know how to read this:

First of all, it's telling you that is an exponent,
since it says "y = log(something)"
Then it tells you that when you raise the base to
the exponent , the result is
Putting all that together:

You can also express as

The rule for this is to multiply the exponents

You can solve this on a calculator, or
take the log to the base of both sides

Actually,

and, as I showed,

Rewrite this in exponential form:--->
Now take the common log (base = 10) of both sides.
Use you calculator to find these logs. First apply the power rule for logarithms to the left side.
Divide both sides by .
Use your calculator to find the logs.
