To arrange the numbers in descending order, we need to convert them to a common format. Here are the numbers rewritten in decimal form:

1. \( 5.9 \times 10^{-5} = 0.000059 \)
2. \( 5.6 \times 10^{-6} = 0.0000056 \)
3. \( 3.9 \times 10^{-6} = 0.0000039 \)
4. \( 6.5 \times 10^{-4} = 0.00065 \)

Now we can compare the decimal values:

1. \( 0.00065 \)
2. \( 0.000059 \)
3. \( 0.0000056 \)
4. \( 0.0000039 \)

Arranging these in descending order gives us:

1. \( 6.5 \times 10^{-4} \)
2. \( 5.9 \times 10^{-5} \)
3. \( 5.6 \times 10^{-6} \)
4. \( 3.9 \times 10^{-6} \)

Thus, the final answer in descending order is:

**6.5 * 10^-4; 5.9 * 10^-5; 5.6 * 10^-6; 3.9 * 10^-6**.
