The spoke of a wheel reaches from the center of the wheel to its rim. if the circumference of the rim of the wheel is 48 inches, how long is each spoke? use 3.14 for π, and round your answer to the nearest hundredth.
a. 12 inches
b. 7.64 inches
c. 15.29 inches
d. 8 inches

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)

step-by-step explanation:

the answer is simply just 6n add the two together as they have an n
