Since the derivative of x^1 is x^2, is it correct to then work it further to get the "best answer" as
1/sqrt x
and then rationalize the denominator by multiplying by 1 as in
(1/sqrt x) * (Sqrt x/Sqrt X)
to get
Sqrt x / x ???

Best ResponseYou've already chosen the best response.1that probably depends on your teacher? Rationalizing it is certainly not incorrect.

Best ResponseYou've already chosen the best response.1ask him/her then to be sure. In my class I could leave it as x^1

Best ResponseYou've already chosen the best response.0This is my first negative exponent in a derivative. Wondering if it needs to be left as it comes out of the rule, or further refined to rationalized denominator form.

Best ResponseYou've already chosen the best response.1In my textbook they leave it as a negative exponent, but that might be because of space considerations. Seriously, just ask your teacher.
