SOLVING EXPONENTIAL EQUATIONS


Note:

If you would like an in-depth review of exponents, the rules of exponents, exponential functions and exponential equations, click on exponential function.



Solve for x in the following equation.

Example 4:tex2html_wrap_inline155tex2html_wrap_inline113


Isolate the exponential term.


eqnarray27


eqnarray31





You can also check your answer by graphing tex2html_wrap_inline125 (formed by subtracting the right side of the original equation from the left side). Look to see where the graph crosses the x-axis; that will be the real solution. Note that the graph never crosses the x-axis. This means that there are no real solutions.
