Rachel is a stunt driver. One time, during a gig where she escaped from a building about to explode(), she drove to get to the safe zone at 24 meters per second. After 4 seconds of driving, she was 70 meters away from the
safe zone.
Let y represent the distance (in meters) from the safe zone after a seconds.
Complete the equation for the relationship between the distance and number of seconds.

step-by-step explanation:

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)
