The function y = 3.75 + 2.50(x - 3) can be used to determine the cost in dollars for a uber ride of x miles. what is the rate of change of the cost in dollars with respect to the number of miles? explain how you got your answer. multiple choices: a. $3.75 per mile b. $6.25 per mile c. $4.75 per mile d. $2.50 per mile

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)
