Certainly! Here are the numbers written using decimals in scientific notation:

6. $$4,\!230,\!000 = 4.23 	imes 10^{6}$$

7. $$12,\!980,\!000,\!000 = 1.298 	imes 10^{10}$$

8. $$6,\!070,\!000 = 6.07 	imes 10^{6}$$

**Explanation:**

- **Scientific Notation** is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It is written as the product of a decimal number (between 1 and 10) and a power of ten.
  
- For example:
  - $$4,\!230,\!000$$ can be written as $$4.23 	imes 10^{6}$$ because you move the decimal point 6 places to the left to get 4.23.
  - $$12,\!980,\!000,\!000$$ becomes $$1.298 	imes 10^{10}$$ by moving the decimal point 10 places to the left.
  - $$6,\!070,\!000$$ is written as $$6.07 	imes 10^{6}$$ by moving the decimal point 6 places to the left.

This notation is especially useful in scientific and engineering contexts where dealing with very large or very small numbers is common.
$$4,\!230,\!000 = 4.23 	imes 10^{6}$$ $$12,\!980,\!000,\!000 = 1.298 	imes 10^{10}$$ $$6,\!070,\!000 = 6.07 	imes 10^{6}$$

Write the following numbers using decimals where necessary: 6. \( 4,230,000= \) 7. \( 12,980,000000= \) 8. \( 6,070,000= \)
