Question

California population is about 39,780,000 in 2020; Los Angeles Country population is about 10,079,000. Write these numbers in scientific notation. About how many times larger is California than LA Country?

Answer 1

In scientific notation, 10^n where n are the terms after the comma, so for California would be:

39780000=39.78x10^6

And for Los Angeles Country:

10079000=10.079x10^6

To know how many times larger is California than LA Country, we just divide them, California is 3.95 times larger than LA Country
