If the number of bacteria in a colony doubles every 162 hours and there is currently a population of 105 bacteria what will the population be in 324 hours from now?
After 162 hours, there will be \(105 \times 2 = 210\) bacteria.
After 324 hours, there will be \(210 \times 2 = \color{brown}\boxed{420}\) bacteria
324 / 162 = 2
105 * 5 2^2 = 105 * 4 = 420
The population of bacteria will have 420
