The differential equation dy dx equals the quotient of the quantity x minus 2 and y minus 2.

I) produces a slope field with horizontal tangents at y = 2

II) produces a slope field with vertical tangents at y = 2

III) produces a slope field with columns of parallel segments

a) I only

b) II only

c) I and II

d) III only

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)
