On Monday, five hundred two students went on a trip to the zoo. all nine buses were filled and seven students had to travel in cars . how many students were in each bus? Pls show work and the check too.

55 students in each bus.

Step-by-step explanation:

Work:

502 students in all

There were 9 buses and 7 students were left

502-7= 495

495/7= 55

55 times 9=495+7=502

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)
