If a stack of 35 coins fits snugly in the coin wrapper​ shown, how thick is 1 coin​? One coin's diameter is 21.17 mm, the wrapper's volume is 26,520 mm to the power of 3.

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:

x+14

step-by-step explanation:

the first one, all those points on the line just make a strait line.
