Concerning your first question, try this:

  (mu*lambda)^(b) - (mu^b)*(lambda^b) // PowerExpand


Concerning the second one, it is not quite clear, what do you have in mind, since this:


E^(a + b)

works. You have probably a more complex example in mind.

Have fun, Alexei

1)  Why does Mathematica not give the value 0 to the expression
(mu*lambda)^(b) - (mu^b)*(lambda^b)? It seems to treat the expression (mu*lambda) as a new variable.
  I used the greek letters from the palette in the actual expression.

2)  Many times I cannot get Mathematica to simplify expressions involving the exponential functions,
  e.g., it won't combine the arguments of the Exp functions. Is there a way to force this?
