    You need to move the decimal till it's between the first and second numbers. Count the number of spaces you have moved it and note it as (whatever the mumber is) x 10^n (n being the number of places you moved the decimal. In this case, you will move your decimal 13 places. So your answer would be 4.81 x 10^13. :)

    so, if you move count from the decimal in 4.81 to the end of the last 0, you get 13

    why is it 4.8 instead of it being 481.?

  16. LoganH

    so it would be \[4.8\times10^{13}\]

    say it is 879000000. you put the decimal after the first number, 8 and stop before the first 0 so 8.79 Any easier?

    then you count the number of digits from the decimal to the end of the last 0

    it is always (number between 1 and 10) * 10^(number of digits counted)
