Let's evaluate each option to determine if they are correct representations of numbers in scientific notation:
1. **0.00045 as 4.5 × 10⁵**: This is incorrect. 0.00045 is equal to 4.5 × 10⁻⁴ in scientific notation, not 4.5 × 10⁵.
2. **0.00045 as 4.5 × 10⁻⁴**: This is correct. 0.00045 can be accurately expressed as 4.5 × 10⁻⁴.
3. **4.5 × 10⁰ as 0.45**: This is incorrect. 4.5 × 10⁰ equals 4.5, not 0.45.
4. **4500 as 4.5 × 10³**: This is correct. 4500 can be expressed as 4.5 × 10³ in scientific notation.
In summary, the incorrect representations of numbers in scientific notation are:
- **0.00045 as 4.5 × 10⁵**
- **4.5 × 10⁰ as 0.45**
So, the correct selections are the first and the third options.
1. **0.00045 as 4.5 × 10⁵**: This is incorrect. 0.00045 is equal to 4.5 × 10⁻⁴ in scientific notation, not 4.5 × 10⁵.
2. **0.00045 as 4.5 × 10⁻⁴**: This is correct. 0.00045 can be accurately expressed as 4.5 × 10⁻⁴.
3. **4.5 × 10⁰ as 0.45**: This is incorrect. 4.5 × 10⁰ equals 4.5, not 0.45.
4. **4500 as 4.5 × 10³**: This is correct. 4500 can be expressed as 4.5 × 10³ in scientific notation.
In summary, the incorrect representations of numbers in scientific notation are:
- **0.00045 as 4.5 × 10⁵**
- **4.5 × 10⁰ as 0.45**
