Plug f(x) as x in g(x) and you get 6(x^2-5), which is g(f(x)) = 6x^2-30.

G(x) = 6x

g(f(x)) 
= 6((x^2) - 5) 
= (6x^2) - 30

so its equal to
(6x^2) - 30

Answer:

4a^4·b^5

Step-by-step explanation:

The applicable rule of exponents is ...

(x^a)(x^b) = x^(a+b)

The commutative and associative properties of multiplication apply, so we can write the expression as ...

4·(a^3·a)·(b^2·b^3) = 4·a^(3+1)·b^(2+3) = 4·a^4·b^5
