You are considering two job offers. The first job pays $15.50 per hour. The second job pays $11.00 per hour plus $1.50 per unit produced per hour. How many units must you produce per hour for the second job to pay more per hour than the first job? You must produce more than
units per hour for the second job to pay more per hour than the first job.

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)
