Final answer:
In the short run, when capital is fixed at 25 units, the firm's production function becomes Q = 2(25^0.5) L^0.5, where Q is the quantity of output and L is the level of labor.
Step-by-step explanation:
In the short run, when the level of capital is fixed at 25 units, the firm's production function can be represented by the equation Q = f[L], where Q is the quantity of output and L is the level of labor. This means that the output only depends on the amount of labor employed.
For example, if the firm hires 10 units of labor, then the production function becomes Q = f[10].
In this case, the specific production function given is Q = 2K^0.5 L^0.5, where K represents capital and L represents labor. Since the level of capital is fixed at 25 units, the firm's short run production function becomes Q = 2(25^0.5) L^0.5.
