Arental car agency charges $ 170.00 per week plus $ 0.15 per mile to rent a car. how many miles can you travel in one week for $ 264.50 question mark
the number of miles you can travel in one week for $ 264.50? ?

630 Miles

Step-by-step explanation:

$264.50 - $170.00 = $94.50

$94.50/$.15 = 630 miles

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)
