derivative of f(x) = x/(sqrt(x^24))

calc  Reiny, Friday, February 6, 2009 at 3:16pm
I would rewrite it as
y = x(x^2  4)^(1/2_
then use the product rule
dy/dx = x(1/2)(x^24)^(3/2)(2x) + (x^24)^(1/2)
we could factor that
dy/dx = (x^24)^(3/2)[x^2 + x^24]
= 4/(x^24)^(3/2)
check my work, I did not write it on paper first, did all the steps as I typed.
