-- f(x) = e^(x^3 + 2)

= 3x^2 e^(x^3 + 2)

-- f(x) = (e^-4x)/(x^3 + 7)

= e^-4x [(-4x^3 - 3x^2 - 28)/(x^3 + 7)^2]

-- f(x) = x^3 ln x

= 3x^2 ln(x) + x^2

-- f(x) = (ln^3 sqrt(x^2))/(x^3)

= (ln)3

-- f(x) = (^7 sqrt(x+8))/(5-6x)^8)

= [(x+8)/(5-6x)^8)] [(1/7) (1/x+8) + (48/5-6x)]

Thanks in advance for any help.
