In Response To 'Re: Reorganizing Polynomial Equation without So...'
---------
If a specific example is needed:

f(xy) = (x + 0.6)^0.57 * (0.7 * y);

I would love an automated way to get:

f'(xy) = f(x) + f(y);

where (for the example case above)

f'(xy) = log(f(xy))

f(x) = 0.57 * log(x + 0.6)

f(y) = log(y) + log(0.7)

Is Mathematica capable of manipulating an equation to generate this? One can imagine how larger equations would quickly become a pain.
