## gabbyalicorn one year ago SCIENTIFIC NOTATION PLEASE HELP! What is 48,100,000,000,000 in scientific notation? ? x 10 ?

1. LoganH

okay

2. LoganH

in scientific notation, the first number can be between 1 and 10

3. BishopPatton

4.81 X 10^ 13

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. :)

6. LoganH

So if you see, a way would be 4.81

7. gabbyalicorn

But, @RainbowBrony555 wheres the decimal? I only see commas...

8. gabbyalicorn

Oh, do you mean 10.?

9. LoganH

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

15. gabbyalicorn

why is it 4.8 instead of it being 481.?

16. LoganH

so it would be $4.8\times10^{13}$

17. LoganH

it has to be between 0 and 10

18. LoganH

Am i confusing you?

19. gabbyalicorn

Well...sort of but maybe if I look at the video that @RainbowBrony555 gave me i would understand the things you are explaining better.

20. LoganH

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

21. BishopPatton

it is pretty easy once you get the hang of it.

22. LoganH

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

23. LoganH

It is.

24. gabbyalicorn

Ah, I see. I get it now. :)

25. BishopPatton

so like you have 724000000 7.24(000000)

26. BishopPatton

yep... he is right

28. gabbyalicorn

cx I got 13, I understand now. ^u^ Thank you! <3

29. LoganH

yes so how many did you count?

30. gabbyalicorn

thirteen.

31. LoganH

No problem! :D

32. gabbyalicorn

:D

33. LoganH

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