Question

What is the scientific notation of 568 billion?

Answer 1

`5.68xx10^11`

Explanation:

1 billion`=10^9`.
568 billion`=568xx10^9`

Now, you need to make the number being multiplied by `10^x` a number between 0 and 10. To do this, divide 568 by 100 to get 5.68, but to keep the same value of the overall number, you need to multiply `10^9` by 100. This is the same as doing `10^9xx10^2=10^11`
