Answer:
5.64 * 10²
Explanation:
The first number in scientific notation has to be a number from 0 to less than 10. Since 564 is bigger then 10, we are going to divide.
564 / 10 = 56.4
56.4 / 10 = 5.64
Since we divided twice to get a number between 0 and 10, that wil be the exponent.
5.64 * 10²
Best of Luck!
