I don't get how to solve an equation when e is in the equation. I know that e = 2.718

Say for example,

How do I solve 5000e^(-.24)?

This is what I got:

5000 x 2.718^(-.24) and then I got stuck.How to do solve when its to the power of a fraction? (i.e. 0.24)?The answer should be approx. 3933.14

Thanks
