Consider the following expression
Var = ( m^((a + b + c)/(3 n + j + d)) k^(a + b))^(f/(a + b));
Then, I take the ratio
and my output is
(k^(a + b) m^((a + b + c)/(d + j + 3 n)))^(f/(a + b))/m^(2/3)
Why Mathematica does not collect the exponents of $m$? It happens a lot of time and I would like to solve.
Which command should I use? Simplify and FullSimplify are not actually working.
