Question

The population of Foxille is about `12 times 10^3` people. Which is another way to write this number?

Answer 1

`12,000` in decimal notation.

`1.2 xx10^4` in scientific notation

Explanation:

`10^3` is the same as `1000`

`12 xx 10^3 = 12 xx 1000 = 12,000`

Not that although this looks nearly the same as scientific notation, the first number would have to be between 1 and 10.

`12 xx10^3 = 1.2 xx 10^4` in scientific notation and

`12,000` as a normal number in decimal notation.
