Jorge is asked to build a box in the shape of a rectangular prism. its height will be 2 cm more than its width. the sum of the length, width, and height is 20 cm. use a graphing calculator to find the width, rounded to the nearest tenth of a cm, that will give jorge’s box the largest possible volume.
a 2.7 cm

b 5.7 cm

c 6.0 cm

d 9.0 cm

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)
