In economics, a production function is a function of capital K and labour L, i.e. Q = f(K, L). The marginal product of capital, MPK, is measured by the first order partial derivative with respect to K, while the marginal product of labour, MPL, is measured by the first order partial derivative with respect to L. Given the production function, Q = 10K^{3/5} L^{2/5}
a) Obtain an expression for the marginal product of capital, MPK.
b) Obtain an expression for the marginal product of labour, MPL.
c) Evaluate MPK and MPL when K = 60 and L = 100. Give your answer to 2 decimal places.
