Question: Suppose the production function is Q = f (K, L). Assuming both inputs are substitutable in production, show that the Marginal Rate of Technical Substitution

Suppose the production function is Q = f(K, L). Assuming both inputs are substitutable in production, show that the Marginal Rate of Technical Substitution (MRTS) is equal to the ratio of the marginal products; specifically, MRTS = - (MP_L/MP_K).
