Step-by-step explanation:
to do standard form you have to move the decimal to after the first number so in this case we would move the decimal 8 places from 298800000.0
to 2.98800000 and we can remove the zeros to make it 2.988
then you will plug the times ten and because we move the decimal over 8 it would be 10 to the power of 8 so your answer would be 2.988*10^8
hope this helps have a good day
