Question

How do I find the derivative of sqrt(x)/x^3?

Answer 1

you could write it as
\[\huge x^{-\frac{5}{2}}\] and use the all mighty power rule

Answer 2

Or, any function can go by logarithmic differentiation (with chain when needed), for people that don't remember quotient, product and other rules.

Answer 3

I am just kidding, of course. Wouldn't use log. differentiation for x^3 :D
