Answer 1

It looks like you've provided a quiz format but did not include all the necessary details for the questions. However, I can help you solve the first question you've mentioned.

### Question 1:
Solve the following:

\[
(2.2 \times 10^{-6}) (8.5 \times 10^{6})
\]

### Solution:
To multiply numbers in scientific notation, you can multiply the coefficients (the numbers in front) and then add the exponents.

1. Multiply the coefficients:
\[
2.2 \times 8.5 = 18.7
\]

2. Add the exponents:
\[
-6 + 6 = 0
\]

3. Combine them:
\[
18.7 \times 10^{0} = 18.7
\]

Thus, the answer is:
\[
\boxed{18.7}
\]

If you provide the details for Questions 2, 3, 4, and 5, I can help you solve those as well!
