Anumber cube was rolled as part of an experiment. the results are in the table below. the fraction startfraction 1 over x endfraction is the experimental probability of rolling a 3. what is x? experiment results number 1 2 3 4 5 6 frequency 4 6 5 7 3 5 2 3 5 6

the answer is b i just did that

step-by-step explanation:

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)
