phi · Answer

what is the definition of e in that formula?

adamaero · Answer

the regular e^4

adamaero · Answer

The person pointed out how I failed to write the original equation with that.

phi · Answer

Just looking at the exponents,  you will get a big number
so wolfram is computing the expression correctly.

If that is not the correct answer, then the original expression is wrong.

adamaero · Answer

frankly, this is suppose to be a ten min problem all together...and it's eating up so much time

phi · Answer

I am wondering how "e" gets into this problem.
I would think you would want mass of electron  (me)  or something like that.  But that is just a surmise on my part.

ya, but I mean it's here too: http://quantummechanics.ucsd.edu/ph130a/130_notes/node98.html

phi · Answer

I think "e" represents the charge on an electron  not 2.7

adamaero · Answer

ok, I don't get why the other guy just didn't say that from the get-go
