When you fold a piece of a piece of paper in half, the thickness of the folded piece is twice the thickness of the original piece. A piece of copy paper is about 0.1 mm thick. Part 1
How thick is a piece of copy paper that has been folded in half 7 times?

The piece of paper is about
1.28
cm thick after being folded 7 times.

Part 2 out of 2
Suppose that you could fold a piece of copy paper in half 12 times. How thick would it be? Write your answer in centimeters.

The piece of paper is about
cm thick after being folded 12 times.

Part A: 6.4 MM Part B: 20.48 CM

Step-by-step explanation:

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)
