1.9 1.5 1.2

1.4 1.3 1.4

a. number of laps
b. distance per minute
c. laps per minute
d. time in minutes

answer:

the correct answer for this question would be:

question - c

answer: the answer is d. do not throw a fit if it is wrong, we all can if we all worked together.

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)
