Question

A firm produces output using labor, L, and capital, K, measured in man-
hours and machine-hours, respectively. The firm’s production function f(L, K) = √ √ LK, with associated marginal product functions MPL = √K and MPK = 2 L√ √L . The price of labor is $10 per man-hour and the price of capital is $40 2 K per machine hour. The firm’s production target is 100 units of output per day.
(a) Does this firm’s cost minimization problem have an interior or a corner
solution? Justify your answer.
(b) How many man-hours and how many machine-hours per day are used
in the firm’s cost minimizing input combination?
(c) What is the minimum cost for this firm of producing 100 units of output
per day? 

*Please fully explain out math process
