This is a solow growth model problem I don't know how to solve this problem(4.1.3.) help me please

This is the Solow Growth Model [8) which models the growth of the ratio of capital to labor under the assumptions given earlier. Summary Assumptions (1) Q = f(K, L) where f (K, L) is a function with constant returns to scale. dlC sQ; a fraction of the production output is invested in capital. dt AL; labor grows according to this equation. dt Definitions we analyze the ratio of capital to labor. g(k) f (k, 1). Result EXAMPLE 4.1.1. = sg(k) Ak dt As an example, let's take the production function to be 1/3 2/3 (4.13)
