Kaya rented a limousine for prom. there was a one-time charge of $150, plus an hourly
rate of $45. her total cost for the night was $347.50. how many hours did kaya rent the limo
for?

Kaya rented the limo for about 4.39 hours

Step-by-step explanation:

set up an equation:

347.50 = 150 + 45x, where x is the number of hours she rented for

solve for x:

195.50 = 45x

x ≈ 4.39

Kaya rented the limo for about 4.39 hours

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)
