A child holds the end of a kite string 36 in. above the ground. The string is taut and it makes a 72° angle with the horizontal. How high off the ground is the kite, if 540 in.
of string are out? Round your final answer to the nearest tenth of an inch.

not sure sorry here is what i got when searching it

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)
