This involves a quick application of the power rule, which is
f'(x)=nx^(n-1).

First, it is helpful to rewrite
f(x)=√(x) as
f(x)=x^{(1)/(2)}. Remember that these are equivalent forms, but the latter is easier to use with the power rule.

We apply the power rule and simply:


(1)/(2)(x)^{((-1)/(2))}=(1)/(2x^(1/2)) = (1)/(2 √(x) )
