I assume you learned about the natural logarithm?
Basically, you want to get the \(\displaystyle e\) part all by itself and then take the Ln of both sides of the equation. When you take the Ln of e, the exponent of e is all that remains. For example:
\(\displaystyle e^{3x}=4 \Rightarrow Ln(e^{3x})=Ln(4) \Rightarrow 3xLne=Ln4 \Rightarrow 3x=Ln4\)
For your problem, distribute the 5000 to the inside terms, then move everything on the left side of the equation over to the right except for the e term and then take the Ln of both sides. You may find it more helpful to divide through by the coefficient of e before taking the Ln since there will be one in this case.
