# Find the derivative of: f(x)= sqrt(x) - 1/sqrt(x) Please include the process.

remember that x^-m=1/(x^m) first, conver to exponential $\sqrt{x} - \frac{1}{ \sqrt{x} } =x^ \frac{1}{2}-x^ \frac{-1}{2}$ now do the thingummy (1/2)(x^(-1/2))-(-1/2)(x^(-3/2)) convert to fraction form $\frac{1}{2 \sqrt{x} } + \frac{1}{2 \sqrt{x^\frac{3}{2}} }$ $\frac{1}{2 \sqrt{x} } + \frac{1}{2x \sqrt{x} }$ dat is the answer
