The population of these two cities combined in scientific notation is 11.9 x [tex]10^{6}[/tex]
Step-by-step explanation:
1a. Population of NYC is 8.1 x [tex]10^{6}[/tex]
1b. Population of LA is 3.8 x [tex]10^{6}[/tex]
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 [tex]10^{6}[/tex] ) + (3.8 x [tex]10^{6}[/tex] )
2b. Take [tex]10^{6}[/tex] common
Total population = [tex]10^{6}[/tex] * (8.1 + 3.8)
Total population = [tex]10^{6}[/tex] * 11.9
Therefore, the population of these two cities combined in scientific notation is 11.9 x [tex]10^{6}[/tex]
