Towanda makes two types of jewelry: bracelets and necklaces. Each bracelet takes her 2 hours to make and each necklace takes 3 hours to make. Towanda has 16 hours available to make jewelry. Write a linear inequality to represent this situation where x represents the number of bracelets and y represents the number of necklaces she makes.

look a the sides they are perpendicular

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)
