Spot builds dog houses. He needs 10 wooden boards and 15 nails to build a small dog house; and he uses 15 wooden boards and 45 nails for a large dog house. Spot makes $40 profit on every small dog house and $52 profit on every large dog house. If he has 60 wooden boards an 135 nails, how many LARGE dog houses should he make to maximize his profit?

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)
