Question

0.000301 in scientific notation?

don't understand

Answer 1

`=3.01e-4`

Explanation:

We can start out by writing the number in standard form, which means that it shouldn't exceed `10`. So in this case, we are writing it as `3.01 \cdot10^(-4)` instead of `30.1*10^(-3)`.

The only difference standard form is to scientific form, is that we are writing the `10^(-4)` to be `e-4` instead.

Answer 2

`3.01*10^-4`

Explanation:

The first thing you should to know is that scientific numbers are between 1 and 9

so move the dot 4 digits to the right

`00003.01`

zeros on the left of the number you can remove them

`cancel(0000)3.01`

the multiply the number by 10 to the power of (how many digits you've moved the dot)

so

`3.01*10^-4`

negative 4 because you moved the dot to the right if you move it to the left the power will be positive like

`32000` = `32000.0` = `3.2 * 10^4`
