Answer:
1.9 * 10 ^ 3
Explanation:
1900
To change into scientific notation, we need it in the form
a * 10^b
where a is a number between 1 and less than 10
We move the decimal to get the number in the correct location
1900.
1.900 (we can drop the extra zero's)
We moved it 3 places to the left, which means b is 3. We moved it to the left which means we need to make the 3 positive
1.9 * 10 ^ 3
