Explanation / Answer

F(x) = f(x^9)

F'(x) = f'(x^9) (9x^8)

Or F'(a) = f'(a) (9a^8)

Given that f'(a) = 3 and a^8 = 4

Substitute to get

F'(a) = 27(4) = 108

------------------------------------------------

G(x) = {f(x)}^9

G'(x) = 9{f(x)}^8 f'(x)

G'(a) = 9{f(a)^8 f'(a)}

=9 (2)^8 (3)

= 27(256)

=6912
