At Brantley's Bakery, a batch of cookies requires 2 cups of flour and 60 minutes to bake. A cake requires 3 cups of flour and 45 minutes to bake. Brantley has budgeted for 30 cups of flour per day. He
can bake for up to 9 hours per day. Brantley makes the same amount of profit when he sells a batch of
cookies as he does when he sells a cake. How many batches of cookies and how many cakes should
Brantley make each day to maximize his profit?

1. Variables; x=? y=?
2. Constraint:?
3. Determine the vertices of the feasible region.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
