Question

How do you write `87,560` in scientific notation?

Answer 1

`8.756 xx10^4`

Explanation:

first thing is that you'd need to find where your decimal point is.
so we write,
87,560.00

then we move the decimal point between the first and second digit from the left which is between 8 and 7.
8.756000

then we count how many decimal places we ran past by.
(we passed by four decimal places)
`8.756000xx10^"the number of decimal places we passed by"`

we then drop those unnecessary trailing zeroes [zeroes with no non-zero number at the end]
`8.756xx10^4`
