It can be done just with a large error (although as a physics grad you will know how to calculate the error I assume)
What do i do? PLEASE NEED HELP!
There ae several ways and I guess the best will involve using SciPy/numpy features.
But since i don't know those I'll suggest the old school way which is to multiply your numbers up until they become integers and take advantage of pythons big int feature. You will need to plug all the multipliers into your formula and work out the final multiplier - but that is just exponent arithmetic so should be doable. Finally adjust your answer by the calculated exponent. As I say there will probably be better solutions in the numpy space and hopefully someone else will tell you about them.
The actual equation is below screen shotted
