If the two sides do not have the same base, express each as a power of the same base. Simplify exponents, if necessary, using the rules of exponents. Set exponents equal using the exponential equation property. Solve the equation from Step 3. (Note: for equations such as we need to use a different method because Step 1 is difficult to do.) Example:

Evaluating and solving equations dealing with natural logs What is e ? How did it come about ? How and why do we use it ? Use logarithms to solve problems dealing with exponential growth and decay. What is the defining part of the equation that leads to decay or growth ? What does this do graphically ?
What Are Logarithms? When Do We Use Them?
By introducing logarithms first as a means to solve an exponential equation (because A LOG IS AN EXPONENT), hopefully the idea of using logarithms will be problematized in a much better way.

Nov 20, 2009 · (This is similar to what we are to do in Homework #6, problem 2.) The two sample t test compares mean logs across groups, using the difference in those mean logs as the method of comparison. Hence, we are comparing the log geometric means across groups, using the log ratio of geometric means as the method of comparison.

“log x” is understood to mean “log10x”. (You do not have to write the 10). The LOG key on your calculator gives base 10 logarithms. Ex 1: Evaluate log 8 log108 = y 10y = 8 (This is why we need our calculator!) Evaluate the common logarithms using your calculator. Round to the nearest hundredth.

Logarithms were used to convert multiplication and division to easier addition and subtraction. The slide rule was popular with engineers but even an expensive slide rule could provide only four significant digits and decimal points had to be inserted through estimation. It was only about 35 years ago that calculators became readily available.
