# Bonus Assignment: Cobb Douglas I to Cobb Douglas II

Read the original post on Cobb Douglass II (the sequel). If you can convert Cobb Douglass I to Cobb Douglas II, then you’ll get an extra half-percentage point added to your total.

Specifically, I want you to convert this: to this: .

Leave a comment on the original post using your full name. The first one to get it right gets the bonus. Use (K/L)^alpha, etc. to represent fractions and Greek letters.

This exercise is certainly quite mathematical, and that’s why it’s a bonus. But for those of you who read the text, it’s a simple matter of knowing how to read (and write, of course).

Hint: See page 93 of your text book (Box 4.2).

rewrite K/L as (K/Y) times (Y/L)
Regroup like this: (K/Y)^a (Y/L)^a (E)^1-a

Divede both sides by (Y/L)^a and raise both sides by (Y/L)^a

Then you get Y/L = (K/Y)^a/1-a(E)
