Logs

I did my blog today because i have a volleyball tournment sunday and i won't feel like doin it then. ha ha.

1. Logs are another way to write exponents: logb x = a
As an exponent b^a = x
2. To solve a log you write as an exponent
3. If the base is written for log it's implied to be 10
4. The base of ln is always e
5. If b and x are equal then they cancel along with the log

Example 1: log4 64 = 3
4^3 = 64

Example 2: log5 1/125 = x
5^x = 1/125
x = -3

Example 3: log2 2^8
the log cancels, the 2 cancels, and the other 2 cancels
your answer being = 8
