Exercise 4. (Exercises about the chain rules.) Consider the production function \begin{equation*} F(L,K) = \left(\frac{1}{4}L^{-\frac{1}{4}} + \frac{3}{4}K^{-\frac{1}{4}}\right)^{-4} \end{equation*} Suppose that due to worker recruiting pace and investment conditions, the inputs L and K vary with time t and interest rate r, via the following expressions: \begin{equation*} L(t,r) = 6t^2 + 250r \quad \text{and}\quad K(t,r) = \frac{10t^2}{r} \end{equation*} (a) Calculate the rate of change of output q with respect to t when t = 10 and r = 0.1. What is the meaning of this rate? (b) Calculate the rate of change of output q with respect to r when t = 10 and r = 0.1. What is the meaning of this rate?

Let G be a group. For any subsets H, K ⊆ G, define HK = {hk | h ∈ H, k ∈ K}, which is clearly a subset of G. If (ab)2=a2b2 for all a, b ∈ G, show G is abelian. If G is abelian, H ≤ G and K ≤ G (fixed subgroups), show HK G. True or false: If H ≤ G and K ≤ G (But without the assumption that G is abelian), then HK G. Give proof or a counterexample.
