Answer :
Answer:
2.24 x 10^3
Explanation:
When writing in scientific notation, you need to simplify the subject till there's only one digit on the left of the decimal point, so in this problem you had to move the decimal point over two more places.
It has already been moved once, shown by the 10^1, so you add 2 to the 10^1 to get 10^3.
