Describe the plane perpendicular to each of the following axes at the given points with a single equation or a pair of equations a. the z-axis at (-4,9, -2) b. the x-axis at (5, 3,2) c. the y-axis at (6,9,-3) a. choose the correct equation of a plane perpendicular to the z-axis. b. choose the correct equation of a plane perpendicular to the x-axis. ○ a. z=2 -axis. c. choose the correct equation of a plane perpendicular to the y

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)

answer: i could not see part the question so ill explain how to get the answer

step-by-step explanation: for instance the distance she travele d is 10 and she traveled the same amout each mile so do 10 divided by how many miles she drove each time and you ge your answer.
