Can anyone help me this is Math Calculus?

Given the function below, complete parts (a) through (c). q=D(x)=xnk, where k is a positive constant and n is an integer greater than 0 . (a) Find the elasticity of the demand function. (b) Is the value of the elasticity dependent on the price per unit? (c) Does the total revenue have a maximum? When? (a) E(x)= (Simplify your answer.)
