Let's break down the tasks from the image:

1. First Column: Convert to Standard Form (Bentuk Baku)

   • 1. $12 \times 10^5$
   • 2. $123 \times 10^{-7}$
   • 3. $4567 \times 10^6$
   • 4. $6.780.000$
   • 5. $78.000.000.000$
   • 6. $0,000678$
   • 7. $0,00000000078$

2. Second Column: Convert to Regular Form (Bentuk Bilangan Biasa)

   • 8. $5.500$
   • 9. $79.999$
   • 10. $150.000.000$
   • 11. $9.876.000.000.000$
   • 12. $0,007777$
   • 13. $-0,000000123$
   • 14. $0,000000000765$

Let’s proceed with the conversions:

First Column (Convert to Standard Form):

1. $12 \times 10^5 = 1.2 \times 10^6$
2. $123 \times 10^{-7} = 1.23 \times 10^{-5}$
3. $4567 \times 10^6 = 4.567 \times 10^9$
4. $6.780.000 = 6.78 \times 10^6$
5. $78.000.000.000 = 7.8 \times 10^{10}$
6. $0,000678 = 6.78 \times 10^{-4}$
7. $0,00000000078 = 7.8 \times 10^{-10}$

Second Column (Convert to Regular Form):

8. $5.500 = 5.5 \times 10^3$
9. $79.999 = 7.9999 \times 10^4$
10. $150.000.000 = 1.5 \times 10^8$
11. $9.876.000.000.000 = 9.876 \times 10^{12}$
12. $0,007777 = 7.777 \times 10^{-3}$
13. $-0,000000123 = -1.23 \times 10^{-7}$
14. $0,000000000765 = 7.65 \times 10^{-10}$

Here are some related questions to further explore the concept:

1. How do you convert between standard form and regular notation?
2. What is the importance of scientific notation in practical applications?
3. How do negative exponents affect the conversion process?
4. What are the common mistakes when dealing with powers of ten?
5. How would you approach very large or very small numbers in scientific fields?

Tip: Always double-check your exponent when converting between forms to ensure the decimal is placed correctly.
