Composition of Functions · Exercise 23

Use each set of functions to find $f\left(g\left(h\left(x\right)\right)\right).$ Simplify your answers.

$f\left(x\right)=x^4+6,$ $g\left(x\right)=x-6,$ and $h\left(x\right)=\sqrt{x}$

Its source prints no answer for this problem, so there's nothing to check against.
