Help, Please The diagram shows the dimensions of a football field surrounded by a track (in brown). The yellow lines separate the field into 3 pieces. Which expression shows the area of the field inside the track?

1) (100 x 50) + (2 x 25 x 3.14) + (2 x 25 x 3.14)
2) (100 x 50) + (25 x 25 x 3.14) + (25 x 25 x 3.14)
3) (100 x 50) + 0.5(25 x 25 x 3.14) + 0.5(25 x 25 x 3.14)
4) (100 x 50) + 0.5(2 x 25 x 3.14) + 0.5(2 x 25 x 3.14)

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)

step-by-step explanation:

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
