Best ResponseYou've already chosen the best response.0(45x^2) (5x3 + 4)2 by using chain rule

anonymous

Best ResponseYou've already chosen the best response.0then the derivative is correct:)

anonymous

Best ResponseYou've already chosen the best response.0the expanded version of = (45x2) * 2(5x3 + 4) + 2(45x) * (5x3 + 4)2

anonymous

Best ResponseYou've already chosen the best response.0did u check the first derivative?

anonymous

Best ResponseYou've already chosen the best response.0but u were gonna do that

anonymous

Best ResponseYou've already chosen the best response.0where did u get 15x2 from

anonymous

Best ResponseYou've already chosen the best response.0it was already simplified in the first derivative

anonymous

Best ResponseYou've already chosen the best response.0= [(45x2) * 2(5x3 + 4)] + [90x * (5x3 + 4)2]

anonymous

Best ResponseYou've already chosen the best response.0open that up = [(45x2) * (10x3 + 8)] + [90x * (25x9 + 40x3 + 16)]

anonymous

Best ResponseYou've already chosen the best response.0open further = = 2250x10 + 450x5 + 3600x4 + 1440x

Best ResponseYou've already chosen the best response.0u know how to apply chain rule?

anonymous

Best ResponseYou've already chosen the best response.0you said product rule i think thats where i made the mistake

anonymous
