To convert a number in scientific notation to expanded form, you need to move the decimal point to the right or left based on the exponent.

In this case, we have 1.37 x 10^-3. The negative exponent indicates that we need to move the decimal point three places to the left.

So the expanded form of 1.37 x 10^-3 is 0.00137.

Therefore, the correct answer is 1.) 0.00137.
