HELP ME PLZ will give you points!! Gianna Is going to throw a ball from the top floor of her school. When she throws the ball from 192 feet above the ground, the fraction h(t)=-16t^2+16t+192 models the height, H, of the ball above the ground as a function of time, tea. When will the ball hit the ground? Write your answer in complete sentences and make sure to write the units

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)
