Mrs. ikeda manages a restaurant which is currently hiring. on friday she interviewed 1 dishwasher and 2 chefs. on saturday she interviewed 4 dishwashers and 4 chefs for employment. how probable is it that the first person she interviewed on both friday and saturday was a dishwasher?

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)
