Answer:
1.6 X 10^3
Explanation:
1,600 is 1.6 X 10^3 in scientific notation because for it to be in scientific notation you need to move the decimal so there is only one whole number. Therefore you would move the decimal three times to the left and 10 would have the exponent positive 3 because if the decimal is being moved to the left, the exponent will be positive.
