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?
