Here are 5 related questions:

1. How do you convert a large number like 7,000,000 into scientific notation?
2. How can you express $5.6 \times 10^{-4}$ in standard form?
3. What are the benefits of using scientific notation for very large or small numbers?
4. How do you convert $1.25 \times 10^3$ to standard form?
5. What is the difference between positive and negative exponents in scientific notation?

Tip: Scientific notation is very helpful for working with extremely large or small numbers, as it makes calculations simpler and reduces errors when dealing with many zeroes.
