Question: division of the center term of an expression

Hello people in mapleprimes,

I have a question.
I want to modify

a := rho^(epsilon-1)*a__01^(-k)*(N__E2/Omega+N__E1*mu)*(K+1)/mu;
to
b:=rho^(epsilon-1)*a__01^(-k)*(N__E2/(Omega*mu)+N__E1)*(K+1);

But, I can't do that modification.

The key term is
c:=N__E2/Omega+N__E1*mu;

I know how to use applyop, but even if I use it, I couldn't obtain b.

Please teach me about this.
