# What is the scientific notation of 568 billion?

$5.68 \times {10}^{11}$
1 billion$= {10}^{9}$.
568 billion$= 568 \times {10}^{9}$
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 ${10}^{9} \times {10}^{2} = {10}^{11}$
