Answer 1

To rewrite \( \log(1/100) \) using the Power Rule of Logarithms, we can follow these steps:

1. Recognize that \( \frac{1}{100} \) can be expressed as \( 100^{-1} \).
2. Apply the log property: \( \log(a/b) = \log a - \log b \).
3. Thus, we have:
\[
\log(1/100) = \log(100^{-1}) = -1 \cdot \log(100).
\]
4. Since \( 100 = 10^2 \), we can further write:
\[
\log(100) = \log(10^2) = 2 \log(10).
\]

Combining these, we get:
\[
\log(1/100) = -1 \cdot 2 \log(10) = -2 \log(10).
\]

So, the correct numerical analysis is:

**−2log10 (negative 2 logarithm 10)**.
