Darell joined a book club to spend more quality time with his cousin. ​ ​At the first meeting, club members recorded how many hours a week they typically read and whether they preferred E-readers or paperback books. ​ ​ ​Find the number of people who read E-readers and Paperback books about 1 hour per week. ​ ​

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)
