A proportional relationship is shown below. Number of pizzas (n) Cost, in dollars (C)
3 24
5 40
7 56

Write an equation that represents the relationship between C and n.

Explain what this equation means in terms of the cost of the pizzas.

A. C=N×8

The amount of pizzas times by 8

Step-by-step explanation:

Because 24÷3=8 So 8 dollars per pizza

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)
