Logs and Exponents

-You can use logs to write exponents. 

Written as log: logbx=a

Written as exponent= b^a=x

-When solving a log, you write it as an exponent

Example 1: log3 5= 56

3^56=5

Example 2: log2 3=6

2^6=3

Example 3: log7 9=12

7^12=9

-If the base is written for log, its 10. 

-The base of ln is always e

-The log cancels, if the base and other number are the same. 

Example 4: log3 3^2

log3 3^2=2
