Question

How do you write 0.000054 in scientific notation?

Answer 1

`5.4 xx 10^-5`

Explanation:

Scientific notation is a way to use rename really large, or really small numbers so that they are easier to use.

Your number is really small:

`0color(red)"."0000color(red)"5"4`
`color(white)"x"=>`

We are going to move the decimal place to the right to remove all of the `0's`. Put your finger at the decimal place and move it all the way until the 5. You should have moved `5` spaces.

Put the decimal there and you should have:
`5.4`

Now since we moved `"5 spaces to the right"` we are going to add a negative exponent to ten:
`5.4 xx 10^-5`
