Khan Academy Logarithm introduction

I will be in algebra 2 trigonometry honors next year and after speaking to some students currently in the class. Have been informed that Logarithms are an important factor. Since I currently am in Geomentry this could prove to be a very helpful introduction to what is to come.

Reflection:
Logarithm (Log)-the inverse of taking an exponent of somethig.  EX: 23=8   Log28 =3 

Log28=3 

Another fun example :) Log464=X or 4x=64 Since 4 to the third power equals 64 Log464=X=3
 or Log464=3

I am find this site to be a great way to learn a lesson if you are sick.
