Let's convert the numbers given in the image into scientific notation:

1. **\( 780,000 \)**  
   In scientific notation:  
   \[ 7.8 \times 10^5 \]

2. **\( 83,256 \)**  
   In scientific notation:  
   \[ 8.3256 \times 10^4 \]

3. **\( 0.225 \)**  
   In scientific notation:  
   \[ 2.25 \times 10^{-1} \]

4. **\( 0.000000678 \)**  
   In scientific notation:  
   \[ 6.78 \times 10^{-7} \]

5. **\( 0.0042 \times 10^3 \)**  
   This is already partly in scientific notation, but the \( 0.0042 \) can be expressed as \( 4.2 \times 10^{-3} \), so the final notation becomes:  
   \[ 4.2 \times 10^0 \]  
   Which is simply \( 4.2 \).

6. **\( 491 \times 10^{-5} \)**  
   The \( 491 \) can be written as \( 4.91 \times 10^2 \), so the final expression becomes:  
   \[ 4.91 \times 10^{-3} \]

7. **\( 67,200 \times 10^{-9} \)**  
   The \( 67,200 \) can be written as \( 6.72 \times 10^4 \), so the final notation is:  
   \[ 6.72 \times 10^{-5} \]
