In a petri dish, a certain type of bacterium doubles in number every 45 minutes. There were originally 32, or 2^5 bacteria in the dish. After 180 minutes, the number of bacteria has doubled 4 times, multiplying by 2^4. Now the population of bacteria is 2^5 • 2^4. Expressed as a power, how many bacteria are in the petri dish after 180 minutes?
A.) 2^4
B.) 2^20
C.) 4^9
D.) 2^9
