II. Suppose the production function for DVDs is given by Q = KL^2 − L^3 , where Q is the number of disks produced per day, K is quantity of capital, and L is quantity of labor. 

1. a) Find marginal product of labor and marginal product of capital. 
2. b) What is the general equation for the isoquant corresponding to any level of output Q? 
3. c) What is MRTSlk here 
4. d) Find elasticity of substitutions L for K here
