There has been a similar question, but it doesn't solve my problem.
I have this input:
var = Exp[a] Exp[b]
And the output is
E^(a + b)
What I actually would like to have is just
var = E^(a)E^(b)
Is there a way to tell Mathematica to stop doing this simplification?
I tried with HoldForm, or Defer, but I actually need to operate on the variable, and those functions do not allow that. My idea would be to use SetSystemOptions, but I haven't found an option that relates to this simplification.
Thanks for any help.
