Find the derivative of f(x)=1/3 sqrt x.
The 3 is little above the square root.
I know that it is 1/3x^4/3. Can this be written as 1/3x^4/3 ?

So I read this as
f(x) = x^(1/3)
f '(x) = (1/3)x^(4/3)
which could be written as 1/(3x^(4/3)
why do you have a negative sign in front? 
I had the negative sign there because thatg was one of the answer choices that best fit what I had but there is no negative correct? Its positive?
