Answer:

3.9602 x 10^2

Step-by-step explanation:

You would first multiply the two together, making sure to put it in correctly on your calculator. Then that would lead you to " 396.04".

Since scientific notation must be between 1-10 you would move the decimal two spots to the left to make it smaller, then keeping in mind that to get it back where it was you must multiply the 10 by a positive two to bring it back a positive two spots.
