What effect a marginal increase in k have upon mpl function

Question

Problem

1. For the production function Q = 8K^0.6L^0.5 derive a function for the slope of the marginal product of L. What effect will a marginal increase in K have upon this MPL function?

2. Derive all the second-order and cross partial derivatives for the production function Q = 35KL + 1.4LK² + 3.2L² and interpret their meaning.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
