Below is an example of an output from a FourierTransform[].

It is technically a correct answer but there is no reason that I can see for it not to cancel the 10^330 's on the top and bottom. Personally I prefer not to have googols in my equations unless absolutely necessary :) (My current record is 10^2397) So far I've tried every command I can think of to make it cancel, why does Mathematica do this? and is there a command I can use to cancel out the factors?

Thanks,
Michael
