The expression in the image is:

\[
(3.5 \times 10^7) + (7.1 \times 10^9)
\]

To add these two numbers in scientific notation, they need to have the same power of 10. 

### Step 1: Convert \(3.5 \times 10^7\) to the same power of 10 as \(7.1 \times 10^9\).

We can express \(3.5 \times 10^7\) as:

\[
3.5 \times 10^7 = 0.035 \times 10^9
\]

### Step 2: Add the two terms:

\[
(0.035 \times 10^9) + (7.1 \times 10^9) = 7.135 \times 10^9
\]

So, the final result is:

\[
7.135 \times 10^9
\]
