A study has demonstrated that the more television a person watches, the lower that person’s level of physical fitness. However, Pablo has experienced the exact opposite effect. The more television he watches, the greater his level of physical fitness. This is because Pablo watches television while running on a treadmill. Based on these facts, which is the most valid conclusion?
A) Watching television causes lower physical fitness.
B) Watching television causes greater physical fitness.
C) Running on a treadmill causes lower physical fitness.
D) Running on a treadmill causes greater physical fitness.

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)
