If you rewrite the function as

h(x) = 10(x^-0.5) - 2x

you might be able to see how to do it from there.

If not.... look below.

{h'(x) = -5(x^-3/2) - 2} - Nov 1st 2005, 07:46 AMbentry this
h(X) = (10/sqrt(X)) - 2X

= 10X^-0.5 -(2X)

d/dx = -5X^-3/2 - (2)

= -(5/sqrt(X^3)) -2 - Nov 1st 2005, 12:34 PMJamesonQuote:

Power rule my friend.

You're finding $\displaystyle \frac{dh}{dx}$, just for notation's sake.
