Question
find g'(t) if g(t) = te(e-1) [it reads t to the exponent of e times e to the exponent -1
Was thinking that e is a constant so the power rule might apply and would end up with -e(ln(te-1)).

-----------------------------------------
If you mean:

g(t) = t^e e^-1,

that is
t^e
g(t) = -----
e

Now the 'e' on top is an exponent for base t, the variable, so yes, the power rule would apply.
But the 'e' on the bottom is simply a constant coefficient.

So you should get:

e t^(e-1)
g'(t) = ---------
e

= t^(e-1)  or t^e/t, if you like.
