What is the electromagnetic flux coming from the surface of a 5000K blackbody? I am supposed to use maxwells equation.

Maxwell came up with four famous equations, but none of them will tell you the answer. Perhaps your teacher does not know that.
What you want is called the StefanBoltzmann equation.
W = (sigma)*T^4
The units will be watts per square meter.
Look it up, if you've never heard of it.
The "electromagnetic flux" you will get will include all frequencies, with about half of the radiation emitted as visible light, at that temperature. 
By the way, your question is about phycics, not algebra, nor algebral.
