Question

How do you write `13,400` in scientific notation?

Answer 1

`1.3400xx10^4`

Explanation:

Scientific notation is of a format where there is just 1 non zero value to the left of the decimal point and everything else to the right of it.

By changing the number in this way we change its value. Consequently a mathematical correction is included in the answer but not applied.
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Given: 13400.0

`" Number Correction"`

`" "13400.0" "xx1`
`" "1340.0" "xx10`
`" "134.0" "xx100`
`" "13.4" "xx1000`
`" "1.34" "xx10000`

But instead of writing the correction as `10000` we write it as`10^4`

So `13400` is the same value as `1.3400xx10^4`
