Best ResponseYou've already chosen the best response.1Take the derivative of f'(x). Use product rule along with chain rule. f'(x)=f'(x)g(x) + f(x)g'(x).

Best ResponseYou've already chosen the best response.1(3sqrtX)'(X^3 2sqrtX +6)+(3sqrtX)(X^3 2sqrtX +6)' \(\cfrac{3}{2\sqrt{x}}\) (X^3 2sqrtX +6)+ \(3\sqrt{x}\ (3x^2 \cfrac{1}{\sqrt{x}})\)

Best ResponseYou've already chosen the best response.1marmots make sure to regard the sqrt(x) as (x)^1/2. It makes it easier to integrate. Just a tip.
