Here are the expressions matched with their correct Scientific Notation:
1. **.55 × 10^9** - This is already in Scientific Notation.
2. **49** - This can be expressed in Scientific Notation as **4.9 × 10^1**.
3. **397.3 × 10^−1** - This can be expressed in Scientific Notation as **3.973 × 10^2** (since 397.3 divided by 10 becomes 39.73 and moving the decimal point to the right increases the exponent of 10).
4. **499 × 10^7** - This can be expressed in Scientific Notation as **4.99 × 10^9** (since 499 × 10^7 equals 4.99 × 10^2).
5. **0.000236** - This can be expressed in Scientific Notation as **2.36 × 10^−4**.
So, the matched expressions in Scientific Notation are:
- 0.000236: 2.36 × 10^−4
- 49: 4.9 × 10^1
- 397.3 × 10−1: 3.973 × 10^2
- 499 × 10^7: 4.99 × 10^9
- .55 × 10^9: .55 × 10^9 (already in scientific notation)
1. **.55 × 10^9** - This is already in Scientific Notation.
2. **49** - This can be expressed in Scientific Notation as **4.9 × 10^1**.
3. **397.3 × 10^−1** - This can be expressed in Scientific Notation as **3.973 × 10^2** (since 397.3 divided by 10 becomes 39.73 and moving the decimal point to the right increases the exponent of 10).
4. **499 × 10^7** - This can be expressed in Scientific Notation as **4.99 × 10^9** (since 499 × 10^7 equals 4.99 × 10^2).
5. **0.000236** - This can be expressed in Scientific Notation as **2.36 × 10^−4**.
So, the matched expressions in Scientific Notation are:
- 0.000236: 2.36 × 10^−4
- 49: 4.9 × 10^1
- 397.3 × 10−1: 3.973 × 10^2
- 499 × 10^7: 4.99 × 10^9
- .55 × 10^9: .55 × 10^9 (already in scientific notation)
