Answer:
6^5, 6^n
Explanation:
To start we can make a quick table of values to determine a relationship:
cut # | # of pieces of paper
1 | 6
2 | 36
3 | 216
4 | 1296
5 | 7776
a) The relationship, as we can see, is powers of 6. Each time we back the cuts, we get 6 times more pieces. So to get the number of pieces after 5 cuts we can do 6^5. There are 7776 pieces of paper.
b) for the nth cut, we replace 5 with n, so 6^n
