Question

How do you write `0.000043` in scientific notation?

Answer 1

`4.3xx10^(-5)`

Explanation:

In scientific notation, a number is written in the form `axx10^n`, where `1<=a<10` (this means number has single digit to the left of decimal point) and `n` is an integer.

Hence, `0.000043` can be written as `4.3xx10^(-5)`.

Note that decimal point has moved five points to the right.
