Your given the firm production function Y= L^0.5 , were Y is quantity of output, L number of labour.

a) find production demand fuction for labour, show your working clearly

b) If the wage rate is $10, what is the optimal level of labour?

a) Production demand function for labour:

Y = L^0.5

L = Y^2

Therefore, the production demand function for labour is L = Y^2.

b) If the wage rate is $10, the optimal level of labour is given by the equation:

Wage rate = 10 = L^0.5

L = 100

Therefore, the optimal level of labour is 100.
