Imagine a 10 by 10 square with the outside edge colored red. Without using paper or counting them individually how many red squares will there be. 2. Explain why you think your answer is correct. How did you "see" it? 3. What if it was a 100 by 100 square? How many red squares would there be? 4. What mathematical expression could you use to represent the number of red squares for any size rectangle?

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)

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
