The US postal service delivered 7.14 * 10 ^ 10 pieces of mail in the month of December and 3.21 x 10 ^ 10 in the month of January. What is the total mail delivered for these two months?

1 answer

To find the total mail delivered for December and January, you simply add the two values together:

7.14 * 10^10 + 3.21 * 10^10 = 10.35 * 10^10
= 1.035 * 10^11

Therefore, the total mail delivered for December and January is 1.035 x 10^11 pieces.
