Question

y = (8(9x)^4+5)^3 Find the derivative. The problem also advises us to use the scaling and shifting rule to compute this derivative. Please help. Will give out a medal. Thank you.

Answer 1

chain rule twice

Answer 2

3(8(9x)^4+5)^2 *(4*8(9x)^3)*9

Answer 3

d/dx[f(g(x))]=f'(g(x)) * g'(x)

Answer 4

what u have is

Answer 5

you can break your function into 3 functions of x basically
