Charlie 8. Charlie is in a hot air balloon above Regina, SK. His friends David and
Eva are watching from the ground, David and Eva are standing 100 ft
apart, and the angle between Charlie's line of sight to the two of them
is 11" Eva is 505 ft from the balloon. What is the angle of elevation of
David's line of sight to the balloon?

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)
