Consider the Cobb-Douglas Production function:

$\displaystyle {P}{\left({L},{K}\right)}={17}{L}^{{0.8}}{K}^{{0.2}}$
Find the marginal productivity of labor (that is, $\displaystyle {P}_{{L}}$) and marginal productivity of capital (that is, $\displaystyle {P}_{{K}}$) when 12 units of labor and 11 units of capital are invested. (Your answers will be numbers, not functions or expressions). Give your answer to three (3) decimal places if necessary.

Marginal Productivity of Labor when L is 12 and K is 11 =

Marginal Productivity of Capital when L is 12 and K is 11 =
