Which explanation correctly solves this problem? two cups of flour are needed to make a pie crust. the bakery has 125 cups of flour. how many pie crusts can they make?

62

Step-by-step explanation:

Assuming they have all other ingredients for the crust, if they have 12m cups of flour they can make 62. All you have to do is 125/2 which is 62.5. Then you round down since they cant have extra flour or make half a pie crust.

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)
