Two bakeries sell muffins that can be customized with different kinds of berries. berry bakery sells muffins for $14.50 a dozen, plus $0.50 for each kind of berry added. raisin bakery sells muffins for $12.00 a dozen, plus an additional $0.75 for each kind of berry added. let b be the number of the kinds of berries added. the equation that represents when the cost of one dozen muffins is the same at both bakeries is 14.5 + .5b = 12 + .75b.

its B It gives the number of the kinds of berries needed for the cost to be the same at both bakeries.

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)
