Question

The population of a country in 1950 was 6.2X10^7. The population in 2030 is projected to be 3X10^2 times the 1950 population. If the projection is correct, what will the population of the country be in 2030?

Answer 1

[6.2x10^7]x[3x10^2]
=1.86x10^10

The hint is in the question. All you do is times the projection in 2030 with 1950 population.
