Question

How do you write `1440000` in scientific form?

Answer 1

`1.44 xx 10^6`

Explanation:

`1440000`

`color(blue)1color(red)(440000)`

There `color(blue)1` gets written first, followed by a decimal and the remaining numbers. There are `color(red)6` digits following the `color(blue)1`, which will be the power of `10`. We keep non-zeroes (`color(orange)44`) explicitly to ensure that the original number and the number in scientific notation have equal significant figures.

`color(blue)(1).color(orange)(44) xx 10^color(red)6`
