Let's solve the problem in the image:

The expression to evaluate is:
\[
(1.31 \times 10^5) + (9,500)
\]

### Step 1: Express 9,500 in scientific notation
\[
9,500 = 9.5 \times 10^3
\]

### Step 2: Add the numbers
First, rewrite both numbers in the same power of 10. We want to express both terms with powers of \(10^5\).

\[
9.5 \times 10^3 = 0.095 \times 10^5
\]

Now, we can add the two terms:
\[
(1.31 \times 10^5) + (0.095 \times 10^5) = (1.31 + 0.095) \times 10^5 = 1.405 \times 10^5
\]

### Final Answer:
The sum is \(1.405 \times 10^5\), which matches the option "1.405 x 10^5".
