#3.13 xx 10^-4#


To convert this number to scientific notation, you take this number and move the decimal point after the first number you read that isn't zero.

So since you move the decimal point 4 places to the right to get it after the 3, the exponent is a negative number.

I have written an answer that explains in great detail on how to convert numbers into scientific notation and how to expand them as well. #rarr#
