Question

find the derivitive of 6axe^-3bx

where a and b are constants. I know i need to use product rule and chain rule but i am having trouble working it out

Answer 1

\[f(x)=6axe^{-3bx}?\]

Answer 2

If so,\[f'(x)=6ae^{-3bx}-18axe^{-3bx}.\]

Answer 3

that was wrong^

Answer 4

Whoops, I meant:\[f'(x)=6ae^{-3bx}-18abxe^{-3bx}.\]
