Question

i need help finding the derivative of
y=4x^4+ 8/x^5

Answer 1

quotient rule. \[g(x)f'(x)-f(x)g'(x)\over (g(x))^2\]Its a pain in the butt I know

Answer 2

do i use quotient rule only fr 8/x^5?

Answer 3

i know the first is 16X^3

Answer 4

no
\[(x^5)(16x^3) -(4x^4+8)(5x^4) \over (x^5)^2\]

Answer 5

ooh thx
