Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.

hana wants to buy a charm bracelet. dayton fine jewelry charges $17 per charm, plus $62 for the bracelet. cain jewelers, in contrast, charges $18 per charm and $60 for the bracelet. if hana wants to add a certain number of charms to her bracelet, the cost will be the same at either jewelry shop. what would the total cost of the bracelet be? how many charms would that be?

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)
