Thank your for your video! From this step, pluging the optimal inputs K and L in the production function you can also find the output supply function. In order to find the conditional demand functions for K and L, should you set up the Lagrange C s.t. Q- F(q, l) and find the solutions or is there a faster way?

Tough algebra, but quite helpful video Thank you!

Can't we divide the partial derivative with respect to l and partial derivative with respect to k and set it equal to w/r and solve for l or k. (i.e, mpl/mpk = w/r)
PLEASE REPLY!

Wait, where did the 4 in the equation disappear when you derive in the beginning!?

Hello. I watched your lectures and found these lectures are very helpful. Now i need your help to solve this equation.
If our total cost is TC= Q3 (Q cube) --8Q2 (minus 8Q square) +57Q + 2 and demand function is p = 45 - (minus) 0.5Q.

Then how to find the level of output and price at which the price is maximized?
And
How to find the level of output and price at which total revenues are maximized?
