If i have an function:
$$f(x) = x^a$$
after, i solved an equation:
$$1/x^{an}$$
so, how i can decompose the exponent to get the equation based on my previous function
$$f(x) * x^n$$
this is a error, because $$x^a *x^n = x^{a+n}$$
But i need, $$x^{an}$$
finally, i want decompose the exponent of my solved equation, to work with the equation based on the function $$f(x) = x^a$$
$$ \frac{1}{x^{an}} = \frac{1}{(x^a)^n} = \frac{1}{f(x)^n}. $$
