well since you already did most of the work by assigning a variable to the first expression, its only fair that we do the rest of your homework for you.

ALL of these are simply applications of the "power rule": the derivative of x^n is nx^{n1}. In the first one, n= 1/2, in the second, n= 3/2, in the third, n= 1, in the fourth n= 0, etc.
