Place the numbers in descending order 4.3 x 10^-5 6.4 x 10^-6 4.3 x 10^-6 6.4 x 10^-4

Answer 1

To arrange the numbers in descending order, we first convert them to their decimal forms:

1. \(4.3 \times 10^{-5} = 0.000043\)
2. \(6.4 \times 10^{-6} = 0.0000064\)
3. \(4.3 \times 10^{-6} = 0.0000043\)
4. \(6.4 \times 10^{-4} = 0.00064\)

Now, we compare the decimal values:

• \(0.00064\)
• \(0.000043\)
• \(0.0000064\)
• \(0.0000043\)

Thus, arranging them in descending order, we get:

1. \(6.4 \times 10^{-4}\)
2. \(4.3 \times 10^{-5}\)
3. \(6.4 \times 10^{-6}\)
4. \(4.3 \times 10^{-6}\)

So the final list in descending order is:

1. \(6.4 \times 10^{-4}\)
2. \(4.3 \times 10^{-5}\)
3. \(6.4 \times 10^{-6}\)
4. \(4.3 \times 10^{-6}\)
