Answer 1

Let's match each expression with its correct scientific notation:

1. **.55 × 10^9** → **5.5 × 10^8**
2. **49** → **4.9 × 10^1**
3. **499 × 10^7** → **4.99 × 10^9**
4. **397.3 × 10^{-1}** → **3.973 × 10^2**
5. **0.000236** → **2.36 × 10^{-4}**

So the matches are:

- .55 × 10^9 → 5.5 × 10^8
- 49 → 4.9 × 10^1
- 499 × 10^7 → 4.99 × 10^9
- 397.3 × 10^{-1} → 3.973 × 10^2
- 0.000236 → 2.36 × 10^{-4}
