The table shows the maximum daily temperatures, in degrees Fahrenheit, recorded in a Texas town in May.
84 86 84 88 83 85 90 84 88 84
85 83 85 84 90 84 85 85 83 85
Which data display(s) can be used to find the median of the maximum daily temperatures?
1 box plot

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)
