THANKS
The distance d (in miles) that you can see to the horizon with your eye level h feet above the water is given by d=3h2√. You are standing on a platform. Your eye level is 15 feet above the water. Can you see a ship that is 4.6 miles away?
(the first blank spot in the answer sentence is yes you can see the ship and no you cant see the ship. The options for the second blank in the answer sentence is 3.87, 4.58, 4.74, 6.71)

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)
