a gymnasium is 168 feet long and 96 feet wide. on a blueprint, the gymnasium is 8 inches long. what is the width of the gymnasium on the blueprint?

Scale = 88 feet/5.5 inch = 16 ft/inch or 16 feet = 1 inch

Width = 76 feet x 1 inch/16 feet = 4.75 inches

Hope this help :)

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)
