Solving Exponential Equations
We know that in exponential functions the
exponent is a variable.
When we wish to solve for that variable we have
two approaches we can take. One approach is to
use a logarithm. The second is to make use of
the Equality Property for Exponential Functions.

• The Equality Property for Exponential
• Functions

Basically, this states that if the bases are the
same, then we can simply set the exponents equal.
This property is quite useful when we are
trying to solve equations involving exponential
functions. Lets try a few examples to see how
it works.

Example 1
(Since the bases are the same we simply set the
exponents equal.)
Here is another example for you to try
Example 1a

The next problem is what to do when the bases are
not the same.
Does anyone have an idea how we might approach
this?
8
Our strategy here is to rewrite the bases so that
they are both the same. Here for example, we know
that

Example 2 (Lets solve it now)
(our bases are now the same so simply set the
exponents equal)
Lets try another one of these.
