This question is about the Economic, and I need your help. Thank you very much.

The Widget Co. can produce widgets according to the formula: q=5K_""'L't where q is the output of widgets, and K1 L are the quantities of capital and labor used. {a} Are there constant, increasing or decreasing returns to scale in widget production? Explain. (h) Are there constant, increasing or decreasing marginal products of factors? Explain. {ch In the short run, the amount of capital used by the Widget Co. is xed. Derive the short-min cost function. [Note that the short-run cost function will show (3 as a function of q, K and the factor prices, w and r.} {de Using your answer to {c}, derive the long-nin cost function
