good morning :) The train to Sun City travels 150 miles per hour. How long will a trip take if Sun City is 525 miles away? A. 4 hours B. 3 hours 30 minutes C. 3 hours 15 minutes D. 3 hours

B. 3 hours 30 minutes

Step-by-step explanation:

Time = Distance / Speed

Time = 525 / 150

Time = 3.5

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)
