Challenge Problem Showdown – December 3, 2012

We invite you to test your GMAT knowledge for a chance to win! Each week, we will post a new Challenge Problem for you to attempt. If you submit the correct answer, you will be entered into that week’s drawing for a free Manhattan GMAT Prep item. Tell your friends to get out their scrap paper and start solving!
Here is this week’s problem:

Operation F means take the square root, operation G means multiply by constant c, and operation H means take the reciprocal. For which value of c is the result of applying the three operations to any positive x the same for all of the possible orders in which the operations are applied?
