1. Total population = (2.4 x 10^7) + (4 x 10^5) = 2.4 x 10^7 + 0.4 x 10^7 = 2.8 x 10^7
2. 3.71 x 10^5 + 4.65 x 10^5 = 8.36 x 10^5
3. 7.35 x 10^-7 + 2.16 x 10^-8 = 7.35 x 10^-7 + 0.0216 x 10^-7 = 7.3716 x 10^-7
4. 5 x 10^3 + 3 x 10^5 = 5 x 10^3 + 300 x 10^3 = 305 x 10^3 = 3.05 x 10^5
1. In 2012, the population of NY was about 2.4 x 10^7 and the population of Oregon was 4x10^5. What is the total population of the two states?
2. 3.71 x 10^5 + 4.65 x 10^5
3. 7.35 x 10^-7 + 2.16 x 10^-8
4. 5 x 10^3 + 3 x 10^5 =
