Answer 1

Let's break down each question one at a time.

### Question 1
A) If \( \log x = 0.25 \), we want to find \( \log x 4 \).

Using the power rule of logarithms, we know that:

\[
\log x 4 = \log x (2^2) = 2 \log x 2
\]

However, without knowing \( \log x 2 \), we can't solve this directly. We can convert \( \log x = 0.25 \) into an exponential form:

\[
x = 10^{0.25} = \sqrt[4]{10} \quad \text{(assuming base 10)}
\]

Now, if we need \( \log x 4 \):

1. Find \( \log x 2 \):

\( \log x 2 = \log (x) 2 = \frac{\log 2}{\log x} = \frac{\log 2}{0.25} = 4 \log 2 \) (again using base 10)

2. Now compute \( \log x 4 \):

\[
\log x 4 = 2 \cdot 4 \log 2 = 8 \log 2
\]

For a specific numerical evaluation, we need \( \log 2 \):

Using \( \log 2 \approx 0.301 \):
\[
8 \log 2 \approx 8 \times 0.301 \approx 2.408
\]

However, since the question only asks for the expression in log form, we can give it as:

\[
\log x 4 = 8 \log 2
\]

### Question 2
A) Which of the following is equivalent to \( \log 9 \)?

1. **Option #1: \( \log(3+3) \)**:
\[
\log(6) \quad \text{(not equivalent)}
\]

2. **Option #2: \( 3 \log 3 \)**:
\[
\log(3^3) = \log(27) \quad \text{(not equivalent)}
\]

3. **Option #3: \( 2 \log 3 \)**:
\[
\log(3^2) = \log(9) \quad \text{(equivalent)}
\]

The answer is: **Option #3: \( 2 \log 3 \)**.

### Question 3
A) If \( \log h = 35 \), we want to find \( \log h 3 \).

Using the power rule:

\[
\log h 3 = \frac{\log 3}{\log h} = \frac{\log 3}{35}
\]

Since we need to keep it in a fraction form, the answer is:

\[
\log h 3 = \frac{\log 3}{35}
\]

### Question 4
A) Evaluate \( \log \sqrt{100} 3 \).

First, we find \( \sqrt{100} = 10 \), so we have:

\[
\log_{10} 3
\]

Since we are asked for its numerical value, we calculate:

Using \( \log_{10} 3 \approx 0.477 \):
\[
\log \sqrt{100} 3 \approx 0.477
\]

### Question 5
A) Find the value of \( \log 0.00001 \).

This can be rewritten as:

\[
0.00001 = 10^{-5}
\]

Now we calculate:

\[
\log 0.00001 = \log(10^{-5}) = -5
\]

So the answer is:
\[
\log 0.00001 = -5
\]

### Summary of Results
1. \( \log x 4 = 8 \log 2 \)
2. Equivalent to \( \log 9 \) is **Option #3: \( 2 \log 3 \)**
3. \( \log h 3 = \frac{\log 3}{35} \)
4. \( \log \sqrt{100} 3 \approx 0.477 \)
5. \( \log 0.00001 = -5 \)
