#2.2x10^3#

Explanation:

To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10 (https://janus.astro.umd.edu/astro/scinote/help.html). Here, it is 2.2. While the number of places to the left that you had to move the decimal point is the exponent, which is 3 times, So the exponent is 3 which gives us the answer: #2.2x10^3#
