Answer 1

To compare the numbers written in scientific notation, we can convert them into standard form:

1. \(4 \times 10^8 = 400,000,000\)
2. \(5 \times 10^8 = 500,000,000\)
3. \(8 \times 10^5 = 800,000\)
4. \(6 \times 10^5 = 600,000\)

Now, let's compare the standard forms:

• \(400,000,000\)
• \(500,000,000\)
• \(800,000\)
• \(600,000\)

Clearly, \(500,000,000\) is the greatest.

Thus, the greatest number in scientific notation is \(5 \times 10^8\).
