Let $f(x) = x^{5/2}$, $g(x) = \frac{ (8 x - 5)^{2} }{16}$, and $h(x) = \tan{(3 x)}$. Find values for the constants $A$ and $P$ which result in the simplified expression for $h(x)/f(g(x))$ equal to the combination of functions below: $$\displaystyle \frac{h(x)}{f \left( g(x) \right) } = \frac{ A \tan{(3 x)} }{ (8 x - 5)^{P}}$$ $A =$ , and
$P =$
