The Cobb-Douglas production function for a company building widgets is given by Y = AL K*- where Y is the total number of widgets produced, L is the number of units of labor (in hours, for instance), and K is the amount of capital invested in equipment and so on (in dollars, for instance).

Question
Im working on a study guide for our midterm and I am stuck on the last question. My value of B is .81 and I got 3.69946 for question b. I don't know where to go from there and I'm confused on how to use the value of 3.69946 to write a new equation only in terms of L and K. I'm also confused on how I would approach part d. when it asks to solve for K as a function of L.

For example, if my ID were 951234567 and my discussion section were with Jacob Lebovic
then I would use 3 = 0.67.
We will consider a company with the following numbers for 2019:
• Annual labor of 20 million hours (which corresponds to about 10,000 full-time work-
ers),
• Capital investment of 100 million dollars, and
• Annual output of 1 million widgets.
(a) What is your value of 3?
(b) Use the data above and the Cobb-Douglas production function to compute A to five
decimal places.
(c) Assume that the total output of the company is fixed at 1 million widgets (i.e.,
1000000). Use the value of A you found in the previous part to write the
Cobb-Douglas production equation only in terms of L and K.
(d) Solve the equation you found above for K as a function of L, i.e., as K
(Hint: you will need to use rules of exponents. Your answer should be of the form
f(L) = cLd for some constants c and d.)
(e) Using the function f from the previous part, compute f'(L). (This is called the
marginal rate of technical substitution.)
(f) What does the fact that f'(L) is always negative imply about labor and capital? (Re-
member that we are assuming the total output is constant.) (One or two sentences.)
(g) Compute and write a sentence or two interpreting the valu
106). Include units in your computation and sentence.
