Question

how would you fine the derivative of this please: f(x) = (−9 x^2 + 8)^5 (4 x^2 + 2)^9

Answer 1

looks like a product rule combined with a chain rule problem

Answer 2

use product rule+chain rule

Answer 3

\[[(-9x^2+8)^5]'(4x^2+2)^9+(-9x^2+8)^5[(4x^2+2)^9]'\]

Answer 4

use
\[(gh)'=g'h+h'g\] with
\[g(x)=(-9x^2+7)^5,g'(x)=5(-9x^2+8)^6\times -18x\]
\[h(x)=(4x^2+2)^9,h'(x)=9(4x^2+2)^8\times 8x\]
