Quadrilateral DONE has vertices (-2, -4), (7, -4), (-2, 5), and (7, 5), respectively. a) Sketch a graph of the quadrilateral. b) Classify the quadrilateral as a square, rectangle or rhombus. c) Determine the intersection point of the diagonals

due to unavailability of graph I sketched a rough diagram so hope this ans. helps you dear....take care!

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)
