Consider the following form for the production function of an economy Q = F (K, L,t) where Q, K, L and t denote output, capital, labour and time respectively. If K and L depend only on t, find an expression for dQ/dt in terms of the partial derivatives of the production function and the time derivatives of K and L. Now suppose that K and L have constant proportionate rates of growth m and n respectively. Find the rate of growth of output when the production function takes the following form:

Consider the following form for the production function of an economy
Q = F (K, L,t)
where Q, K, L and t denote output, capital, labour and time respectively.
If K and L depend only on t, find an expression for dQ/dt in terms of the partial
derivatives of the production function and the time derivatives of K and L.
Now suppose that K and L have constant proportionate rates of growth m and n
respectively. Find the rate of growth of output when the production function takes the
following form:
Q=ert KaLB
(r, α, ß > 0).
