A small country had a population of 8.4 x 10^8 in 2010. Since then, the original population has doubled, and an additional 3.7 x 10^9 people have immigrated into the country. What is the population of the country now?

Respuesta :

I'm not 100% sure because it is rare to ask about adding scientific notation but I would answer it like this:

8.4x10^8 +3.7x10^9=

12.1 x 10^17
