What happens to marginal product of capital as k increases

Question

Problem

Suppose that a firm's production function is given by Q = K^0.33L^0.67, where MP_K = 0.33 K ^-?0.67L^0.67 and MP_L = 0.67 K?^0.33L^-?0.33 .

a. As L increases, what happens to the marginal product of labor?

b. As K increases, what happens to the marginal product of labor?

c. Why would the MP_L change as K changes?

d. What happens to the marginal product of capital as K increases? As L increases?
