Answer 1

I think the answer is 10.35×10^10

Answer 2

Answer:

1.035 x 10^11

Step-by-step explanation:

The us postal service delivered 7.14 x 10^10 pieces of mail in the month of December and 3.21 x 10^10 in the month of January. They have asked to find the total mail delivered for these two months.

So in order to find the total mail we have to add the mails. So we get

 7.14 x 10^10 + 3.21 x 10^10

10^10(7.14 + 3.21)

10.35 x 10^10

or we can also write it as 1.035 x 10^11.
