You can put this solution on YOUR website!
Lets find out.
Start with a piece of paper. When you fold this paper in half once, you will now have 2 identical rectangles. A second time will give you 4, a third 8, and a fourth time will give you 16.
The algebraic equation to determine this is:
y=2%5En
Where y is the number of identical rectangles and n is the number of times the paper has been folded in half.
Plugging in the numbers from your equation yields these results:
y=2%5E4
y=2%2A2%2A2%2A2
y=16
Likewise, if you folded the paper in thirds, the equation would be:
y=3%5En
Where y is the number of identical rectangles and n is the number of times the paper has been folded in thirds.
The number of folds you create in the paper for each iteration is the base (2 in 2%5En or 3 in 3%5En.)
Hope this helps.
