1. 5-3 Laws of Logarithms How to simplify equations so to solve.

2. There are 3 Laws of Simplification

3. There is also a Rule This is called the Change of Base Rule: It can be used to convert a problem so that you could solve it on the calculator. It also has extensive use in Calculus in derivatives and integration.

4. How does it work, you ask? First, solve this the normal way. Then, solve using change of base rule (that is, pick a new base – I’d suggest 3) Now, just so you know, if there is no base written down, it means base 10. (yes, write that down!! I’ll fool you with it if you aren’t careful!!

5. Lets try some problems, shall we?
