Darius and Khadija are learning to play chess. Darius's ratio of wins to loses is 2 to 13. Khadija's ratio of wins to loses is 3 to 17. Who has a better winning record? Explain how you know.

table 1

step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

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)
