Carolyn selected a tile randomly from the set shown below. What is the probability that she selected a white tile or a tile with an even number?
12 2 3 1 23 4 1 4
12
13 3 1
3 4 3 4 2 3 1 1
2. 2 1 2 3 1 2 4 3 3
214
1 1 1 2 3 1 2 14 3
3 1 1 3 2 1 4 3 2 4 2 1 3
a. 8/15
b. 1/72
C. 1/4
d. 9/20

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)
