Answer:

#3.5 xx 10^9#

Explanation:

Given: #3,500,000,000#

Scientific notation requires a decimal to the right of the left-most non-zero number.

If there is no decimal, place a decimal to the far-right of all of the numbers: #3,500,000,000.#

Now move the decimal to the left until it resides to the right of the left-most non-zero number. Count how many places the decimal has moved:

#3.500000000 => #decimal moved #9# places

Remove the extra zeros unless this is a measurement: #" "3.5 xx 10^9#
