The expression you need to simplify is:

\[
(6.8 \times 10^6) + (3.4 \times 10^6)
\]

Since both numbers have the same power of \(10^6\), you can factor out \(10^6\) and just add the coefficients:

\[
(6.8 + 3.4) \times 10^6 = 10.2 \times 10^6
\]

Now, let's rewrite the result in proper scientific notation, where the coefficient should be between 1 and 10:

\[
10.2 \times 10^6 = 1.02 \times 10^7
\]

So the simplified expression is:

\[
1.02 \times 10^7
\]
