Best ResponseYou've already chosen the best response.1product rule for this one use \[(fg)'=f'g+g'f\] with \(f(x)=x^8,f'(x)=8x^7,g(x)=e^x,g'(x)=e^x\)

Best ResponseYou've already chosen the best response.1\(\large f'(x) = 8x^7e^x + x^8e^x\) just take the derivative of each term in the sum above using product rule

Best ResponseYou've already chosen the best response.1that is the derivative of the first term, but not f''(x) yet.

Best ResponseYou've already chosen the best response.1good except for the last term in you answer \[f''(x) = 56^6e^x + 8x^7e^x + 8x^7e^x + x^8e^x\]

Best ResponseYou've already chosen the best response.1sorry, missed an x :) \[f''(x) = 56x^6e^x + 8x^7e^x + 8x^7e^x + x^8e^x\]

Best ResponseYou've already chosen the best response.1you may need to gather like terms...

Best ResponseYou've already chosen the best response.1maybe you also need to factor it??? \[f''(x) = 56x^6e^x + 16x^7e^x + x^8e^x\] \[GCF = x^6e^x\]
