Remind yourself of the three axioms of incidence geometry from, I1, I2, and I3 from Euclid's Book 1. Free book found on https://mathcs. clarku. edu/~djoyce/java/elements/bookI/boo kI. html
(a) Draw a model of points and lines in which I1 and I2 are true but I3 is false,
(b) Draw a model of points and lines in which I1 and I3 are true but I2 is false,
(c) Draw a model of points and lines in which I2 and I3 are true but I1 is false

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)
