5) The radius of the Earth is 3958.8 miles. The radius of the Earth's moon is 1079.4 miles.
a) Find the volume of the Earth's moon.
(5 points)
b) Find the surface area of the Earth's moon.
(5 points)
c) How many times bigger is the volume of earth than the volume of the Earth's moon.
(5 points)

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)
