Answer:
1000 * [tex]3^{9}[/tex] Bacteria after 18 hours,
Step-by-step explanation:
The condition given in the problem is that the number of bacterial triple after every 2 hours.
So, after 2 hours, total bacteria= 1000 * 3
So, after 4 hours, total bacteria= 1000 * 3 * 3
Therefore, the general format for the number of bacteria is 1000 * [tex]3^{n}[/tex], where n is the number of times the bacteria has tripled.
In 18 hours, there are [tex]\frac{18}{2}[/tex] ties that the bacteria has tripled.
Therefore, the no. of bacteria after 9 hours= 1000 * [tex]3^{9}[/tex]
