A bunny population is doubling every 2 years. There are currently 45 bunnies. How many will there be in 10 years?

Find the number of doubling periods:
Number of Doubling periods = Time / Doubling period
Number of Doubling periods = 10/2
Number of Doubling periods = 5

Create a function to determine the amount of bunnies after each doubling period:
B(n) = 45 * 2^n

Since we calculated 5 doubling periods, we want B(5):
B(5) = 45 * 2^5
B(5) = 45 * 32
B(5) = 1,440
