Exponential and Logarithmic Functions
Definition of the logarithmic function:
provided 
.
b is called the base of the logarithm. Two common values for b are 10 (common logs) and e (natural logs).
The properties of logarithms (assume 
)
These properties are vital in handling expression and equations involving logarithms or exponential numbers.
For instance if the variable in the equation occurs in the exponent (
) we need a property of equations not yet mentioned. In this case we will take the logarithm of both sides.
Solve: |
|
Take log of both sides. Use a convenient base. |

Using property 3 we get the following. |
