The population of these two cities combined in scientific notation is 11.9 x
Step-by-step explanation:
1a. Population of NYC is 8.1 x
1b. Population of LA is 3.8 x
2.To find total population of the two cities combined,
2a. Add population of NYC and LA
Total population = NYC's population + LA's population
Total population = (8.1 x ) + (3.8 x )
2b. Take common
Total population = * (8.1 + 3.8)
Total population = * 11.9
Therefore, the population of these two cities combined in scientific notation is 11.9 x
