Best ResponseYou've already chosen the best response.0The population is the amount of people, so there would be \[1.3*10^4\] people. Which is the same as 130000.

Best ResponseYou've already chosen the best response.0Should I divide or subtract since its asking how many "more" people are there in algeville ?

Best ResponseYou've already chosen the best response.0@skullpatrol since its subtracting scientific notation it would be 5.6×10³  1.3×10⁴ ?

Best ResponseYou've already chosen the best response.0@skullpatrol I never actually thought of doing that until now because at schooll my math teachers taught me to move the decimal which makes the exponent decrease by one for example instead of 1.3 it would be 13. Because the decimal is moved to right then you would subtract 1 from the ³

Best ResponseYou've already chosen the best response.0\[1.3*10^45.6*10*3=1.3*10*10^35.6*10^3=\left( 1.3*105.6 \right)*10^3\] \[=\left( 13.05.6 \right)*10^3=7.4*10^3=\frac{ 74 }{ 10 }*1000=7400\]

Best ResponseYou've already chosen the best response.0So it would be 1.7 trillion ÷ 290.9
