The Jonesboro Education Department decided to celebrate opening a new school by baking one of the biggest chocolate chip cookies ever made. They hired a local bakery to make a cookie with a diameter of 32 feet. What is the area of the surface of a cookie with a diameter of 32 ft?

(Use 3.14 as an approximation for pi.)

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)
