How do you write #87,560# in scientific notation?
first thing is that you'd need to find where your decimal point is.
so we write,
then we move the decimal point between the first and second digit from the left which is between 8 and 7.
then we count how many decimal places we ran past by.
(we passed by four decimal places)
we then drop those unnecessary trailing zeroes [zeroes with no non-zero number at the end]
