The problem asks you to add two numbers in scientific notation:

\[
(5 \times 10^5) + (3.9 \times 10^5)
\]

### Step-by-step solution:

1. **Combine the coefficients**: Since both terms have the same exponent of \( 10^5 \), you can add their coefficients directly:
   \[
   5 + 3.9 = 8.9
   \]

2. **Retain the common power of 10**: The sum is then:
   \[
   8.9 \times 10^5
   \]

So, the correct answer in scientific notation is:
\[
8.9 \times 10^5
\]

The answer that matches this in the provided options is **8.9 × 10^5**.

5. What is the difference between standard and scientific notation?

**Tip:** Always ensure that numbers you are adding or subtracting in scientific notation have the same power of 10 before combining their coefficients.
