Expert Solution
Step 1

Answer:

Marginal product: marginal product of input refers to the additional output produced by that input when an additional unit of that input is employed.

(a). 

To find the marginal products of inputs let us partially derivate the production function with respect to the inputs.

Q=3K0.4+4L0.3MPK=QKMPK=3×0.4K0.4-1MPK=1.2K-0.6MPK=1.2K0.6And,MPL=QLMPL=4×0.3L0.3-1MPL=1.2L-0.7MPL=1.2L0.7
