Priya's neighbor has a dirt bike that can go 360 in 15 seconds at this rate how long would it take them to ride 3000

125 seconds

Step-by-step explanation:

We can solve this problem with the help of two methods

We can set up this question as a ratio problem:

360 meters__________15 seconds

3000 meters_________x seconds

We can also solve it as a rate problem and still yield the same

x=125

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)
