Verified Answer :

the answer is= 2.5x104=260
                      =3.4x104=353.6

Answer:

The sum of both expressions is 613.6.

Step-by-step explanation:

In this case, first we have to solve each one of the multiplications and then sum the results, this is:

\(2.5*104=260\\3.4*104=353.6\)

Now with the results of the multiplications, we have to sum them:

\(260+353.6=613.6\)

The sum of both expressions is 613.6.
