Please help, thanks~

(a) Given the production function Q = 0.5K0'7L0'3, nd the the partial elasticity of output with respect to the capital and labor inputs. (b) Given Lagrangian function L(3:, y, c, A) = f (3:, y) A(c 9(32, y)). The optimal solution 33*, y" are functions of c. Find the partial derivative of the maximal value function with respect to the parameter c. 8f(m*, 31*) :7 ac ' (c) If y is related to x by y = :12", how will the rates of growth Ty and arm, be related
