It will describe the rule and give some examples of how it works.
Any time you work with expressions that contain exponents, you have to follow a specific set of rules that are not the same as when you are working with expressions that do not contain exponents.
If you need a review on log properties, feel free to go to Tutorial 44: Logarithmic Properties. The only way we can get that variable out of the exponent, when the bases don't match up, is to use logs. When solving an equation, it doesn't matter what you do to the equation as long as you do the same thing to both sides - this keeps both sides equal.
Also, the reason we take the natural log of both sides is because we have the natural log key on the calculator - so we would be able to find a value of it in the end.
Math works just like anything else, if you want to get good at it, then you need to practice it.
Even the best athletes and musicians had help along the way and lots of practice, practice, practice, to get good at their sport or instrument.
This lesson will define how to work with exponential notation and give some examples of how it is used.
