The point (0,5) lies on a circle that is centered at the
origin. Does (-3,-4) also lie on the circle?
1. Identify the radius from the graph.
r= Yunits
2. Determine the distance from the center to
(-3, 4) using the distance formula
distance = y units
3. Compare the radius to the distance. Does the
point (-3,-4) also lie on the circle?

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)
