The coordinates of trapezoid efgh are e(8, 8), f(8, 10), g(1, 6), and h(4, 1). the image of efgh under dilation is e'f'g'h'.

if the coordinates of vertex e' are (4, 4), what are the coordinates of vertex f'?
(2, 6) (4, 6) (2, 5) (4, 5)

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)
