A firm produces output y using two factors of production (inputs), labour L and capital K. The firm's production function is f(L.K) ==In(L) +In(K). The wage rate w = 4 and the rental price of capital r = 4 are taken as parameters (fixed) by the firm. Solve the firm's long run cost minimization problem (minimize costs subject to the output constraint) to derive this firm's demand function for labour L= L(y) and for capital K = K(y), and the firm's long run total cost function C = C(y).

A firm produces output y using two factors of production (inputs), labour Land capital K. The
firm's production function is f(L. K) =In(L)+In(K). The wage rate w = 4 and the
rental price of capital r=4 are taken as parameters (fixed) by the firm. Solve the firm's long
run cost minimization problem (minimize costs subject to the output constraint) to derive
this firm's demand function for labour L= L(y) and for capital K = K(y), and the firm's long run
total cost function C = C(y).
