這題我真的是搞不清楚狀況
不知道要做什麼
我算了三個derivative但是不知道接下來要怎麼辦
Suppose you have a production function P=f(K,L)=K^(a)L^(1-a), where 0小於等於a小於等於1, and K is the capital available and L is the labour available. Suppose that you have a budget constraint pK+qL=B, where p, q, and B are given positive constants. Show that the production P is maximized when K=aB/p and L=(1-a)B/q.
我算出df/dk df/dL 和 df/d入
就不知道要怎麼做了
