Answer:
f(g(x)) = 10x³ +16
Explanation:
Put the function arguments where they go and simplify in the usual way.
f(g(x)) = f(√(5x³)) = 2(√(5x³))² +16 = 2(5x³) +16
f(g(x)) = 10x³ +16
_____
Without knowing what f(x) and g(x) relate to in the real world, it is difficult to say what f(g(x)) represents. It is a composite function in which the value of g(x) is used as the argument for f(x).
