If you don't answer it and just put random stuff for points i will report you.. Sprinklers are arranged in a rectangular yard to spray 15 feet to water the grass.

What area of the grass will not be watered, in square feet? (Use 3.14 for pi.)

A.) 188.4 squared feet

B.) 319.5 squared feet

C.) 387 squared feet

D.) 1026 squared feet ​

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)
