When you are looking for a logarithm you are really looking to find the power that the given base must be raised to produce a given number. If it sounds complicated it'll make more sense after we are done.
Many times you will see log28 = ?
What this is really asking for is 2? = 8. We will determine what power 2 (which is our base) needs to be raised to in order to give us an answer of 8. In this example 2 needs to be raised to the 3rd power (2 * 2 * 2 = 8) so the answer to the problem is 3.
There are a few other rules that I will discuss in the video so be sure to watch and watch closely.
