Arapahoe community college holds evening classes on colorado state history. the director of studies, wishing to know the age distribution of students in the class obtained the following information. ages are rounded to the nearest year. 63 41 28 22 45 30 43 46 35 56 27 29 20 31 19 22 32 55 54 31 63 51 29 19 27 53 51 33 58 29 65 53 56 18 39 19 make a stem and leaf display

The stem and leaf display has been done and attached.

The stem refer to the ten digit and the leaf is the unit digit.

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)
