Let's solve each logarithmic equation step by step using the definition of logarithmic functions.

### Part 9: Solve for $$ x $$

a) $$ \log _{\sqrt{2}} x=6 $$

Using the definition of logarithms, we can rewrite this as:
$$
x = (\sqrt{2})^6
$$

b) $$ \log _{2} 32=x $$

This can be rewritten as:
$$
2^x = 32
$$
Since $$ 32 = 2^5 $$, we have:
$$
x = 5
$$

c) $$ \log _{5} x=4 $$

This can be rewritten as:
$$
x = 5^4
$$

d) $$ \log _{10} 0.1=x $$

This can be rewritten as:
$$
10^x = 0.1
$$
Since $$ 0.1 = 10^{-1} $$, we have:
$$
x = -1
$$

e) $$ \log _{(6)} 2=x $$

This can be rewritten as:
$$
6^x = 2
$$

f) $$ \log _{4} x=2 $$

This can be rewritten as:
$$
x = 4^2
$$

### Part 10: Find the logarithms using given values

Given $$ \log _{10} 2=0.3010 $$ and $$ \log _{10} 3=0.4771 $$:

a) $$ \log _{2} \sqrt{3} $$

Using the change of base formula:
$$
\log _{2} \sqrt{3} = \frac{\log_{10} \sqrt{3}}{\log_{10} 2} = \frac{0.5 \log_{10} 3}{\log_{10} 2}
$$

b) $$ \log _{2} 0.3 $$

Using the change of base formula:
$$
\log _{2} 0.3 = \frac{\log_{10} 0.3}{\log_{10} 2} = \frac{\log_{10} (3/10)}{\log_{10} 2} = \frac{\log_{10} 3 - 1}{\log_{10} 2}
$$

c) $$ \log _{3} 0.6 $$

Using the change of base formula:
$$
\log _{3} 0.6 = \frac{\log_{10} 0.6}{\log_{10} 3} = \frac{\log_{10} (6/10)}{\log_{10} 3} = \frac{\log_{10} 6 - 1}{\log_{10} 3}
$$

d) $$ \log _{2} 108 $$

Using the change of base formula:
$$
\log _{2} 108 = \frac{\log_{10} 108}{\log_{10} 2}
$$

e) $$ \log _{3} 5 $$

Using the change of base formula:
$$
\log _{3} 5 = \frac{\log_{10} 5}{\log_{10} 3}
$$

f) $$ \log _{4} 75 $$

Using the change of base formula:
$$
\log _{4} 75 = \frac{\log_{10} 75}{\log_{10} 4}
$$
