Mike drivers 110 miles in 4 hours . what his rate of changed? explain.

The rate of change in this case is the speed of his car or how many miles he drives in one hour.

He drives 110 miles in 4 hours, which means he will drive 110/4 miles in 1 hour because 4 hours is four times greater than 1 hour.

110/4=27.5 miles

27.5 miles in one hour or 27.5 mph

27.5 mph

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)
