Answer 1

Given:

In 1995, the USPS approximated that they handled 1.8 x 10" pieces of

mail.

In 2010, the USPS reported that they handled 1.7 x 10" pieces.

We will find the differences in the pieces of mail were handled in 1995 than in 2010

$1.8\times10^{11}-1.7\times10^{11}=0.1\times10^{11}=0.1*10\times10^{10}=1\times10^{10}$

So, the answer will be:

There are 1 x 10¹⁰ more pieces of mail were handled in 1995 than in 2010.
