No I don't think its necessary as long as you have the correct number of significant figures in your answers

If we are converting a number like 0.0380 to scientific notation, we do need to include the last zero in the sense that we'd have to write it as 3.80 x 10^2 right?

Correct.

I did similar examples in class.
