Answer:
8.9 10^-3
Step-by-step explanation:
To write something in scientific notation, you need to move the decimal point so there is one and only number before it. You then put the number of spaces that you moved the decimal point (right = negative) (left = positive) on top of a 10^?
In this case, you need to move the decimal point three places to the right (so -3) to get 8.9 10^-3
