Question

How do you write 12 million in scientific notation?

Answer 1

`12` million is `1.2xx10^7` in scientific notation.

Explanation:

`12` million is `12,000,000`. In scientific notation we write a number as `axx10^n`, where `1<=a<10` and `n` is an integer.

As such

`12,000,000`

= `12xx1000000`

= `1.2xx10xx10^6`

= `1.2xx10^7`
