The US postal service delivered 7.14 x 1010 pieces of mail in the month of December and 3.21 x 1010 in the month of January. What is the total mail delivered for these two months?

Respuesta :

102800000000 total mail delivered

Step-by-step explanation

The solution is 1.035 x 10^11. Since the exponents are the same, we can add the bases. The result is 10.35 x 10^10.

Because the base must be greater than 1, but less than 10 we have to move the decimal one place to the left. This increases the exponent from 10 to 11.
