K-pro automotive shop purchases 120,000 oil filters annually which are sold at an average of 400 per day over the course of a year at its national retail outlets. if the annual holding cost is fifty cents per filter, and the ordering cost is $75 per order, what is the reorder point? (assume 300 days in a year and a lead time of 4 days).
a 15 filters
b 400 filters
c 1600 filters
d 6000 filters

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)
