Answer:

#3color(red)(,675,000,000.) = 3.675 xx 10^color(red)(9)#

Explanation:

Scientific notation is a way of writing very big or very small numbers using powers of 10.

It is written in the form:

#n xx 10^x# where #1<=n<10# and #x# is an integer indicating the number of place holders to give a number of the correct size.

This means " There must only be ONE digit before the decimal point.

#3color(red)(,675,000,000.) = 3.675 xx 10^color(red)(9)#

(The decimal point was moved #color(red)(9)# places to the left.)
