you can write R^2e^(-0.001a) as e^(ln(R^2)*-0.001a)
can you take it from there?

I still don't understand what the problem here is. If [itex]x=\exp(0.001a)-R^2\exp(-0.001a)[/itex], then obviously:

[itex]\ln(x)=\ln(\exp(0.001a)-R^2\exp(-0.001a))[/itex].

Am I missing something? :confused:

If you were wondering if it could be simplified at all, the answer is "no".
