To calculate the correct sum from the given options, we'll first clarify the mathematical expressions involved. Assuming each option presents a scientific notation multiplied or summed, we can perform the required calculations.
1. **Calculate each expression:**
- **Option 1:** \(7.3 \times 10^7 + 1.8 \times 10^7\)
- **Option 2:** \(9.1 \times 10^7\)
- **Option 3:** \(9.1 + 10^7\) — note that adding \(10^7\) directly doesn’t connect with scientific notation consideration.
- **Option 4:** \(8.1 \times 10^7\)
- **Option 5:** \(9.1 \times 10^{14}\)
2. **Perform the sum for Option 1:**
\[
7.3 \times 10^7 + 1.8 \times 10^7 = (7.3 + 1.8) \times 10^7 = 9.1 \times 10^7
\]
3. **Compare the result with other options:**
- **Result of Option 1:** \(9.1 \times 10^7\) matches **Option 2** \( (9.1 \times 10^7) \).
Thus, the correct sum is **Option 2: \(9.1 \times 10^7\)**.
