In this lecture you will understand Common Logarithms, beginning with the notion of Base 10. Next, you will cover Equations, Inequalities, and Change of Base for Logarithms. This lesson is finalized with four worked out examples.
equations by taking the common log of both sides of the equation.
You can then use a calculator to get a decimal approximation of the
If you want to get
a decimal approximation of a logarithmic expression, convert the log
expression to a log expression to the base 10 using the change of
base formula. Then use a calculator to evaluate the new expression.
