I think I have the answer to this question but need some help!

Display the final answer in correct scientific notation and show correct number of significant figures in the final answer:

6.0223010000 x 10-24 x 2.222090001 x 10-30

And you think the answer is what?

Well i think the significant figures in the answer is 10, as the LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. But I am not sure how to enter the actual equation into my calculator? So was hoping to see the answer and work backwards! :o)

So i start like this:
6.0223010000 x 10-24 x 2.222090001 x 10-30 (sorry not sure how to make the-24 and -30 small)

Then i do this:

(6.0223010000 x 2.222090001) x (10-24 x 10-30) =

13.38209483 x (10-24 x 10-30)
This is where i get kind of stuck!

Then i get to this step:
13.3820948351123 x 10 -54
