There were 26 people at Charlotte and Oliver's birthday party. The total cost of the party was $1,429.74. How much did each person who attended the party cost?

$54.99/person

Step-by-step explanation:

Divide '26 persons' into the total cost $1,429.74:  we get $54.99/person.

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)
