Write down $d z / d x$ . Don’t write down $f$ and $g$ .

$z = (9 x + 4)^{3/2}$

Problems 17–22 involve three functions $z (y)$ , $y (u)$ , and $u (x)$ . Find $d z / d x$ from $(d z / d y) (d y / d u) (d u / d x)$ .

This exercise builds on another exercise in its source book, which isn't shown here.
