Let's solve these problems from the image step by step.

### Problem 6: 
We are using the logarithmic property \( a^{\log_b} = b \).

For each expression:
- **a.** \( 100^{\log_8} \)
- **b.** \( 32 \)
- **c.** \( 25^{5 \log_8} + 64^{8 \log_5} \)
- **d.** \( 4^{2 \log_7} = 8^{2 \log_2 + 3 \log_5} \)

#### Solution approach:
For **a** and **c**, simplify using \( a^{\log_b} = b \) and for others, apply log properties.

### Problem 7: 
Apply logarithmic properties to simplify each expression:
- **a.** \( \frac{1}{2} \log 128 + 2 \log 9 - 27 \log 4 - 6 \log \frac{1}{3} \)
- **b.** \( 3 \log \frac{1}{9} - 2 \log 8 + 2^{8 \log 27} - \frac{1}{9} \log \frac{1}{3} \)

#### Solution approach:
- Use the power rule, product rule, and quotient rule of logarithms to simplify the expressions.

### Problem 8:
Rewrite the logarithmic expressions into exponential form and solve for \( x \).
- **a.** \( 2 \log x = 3 \)
- **b.** \( 3 \log (2x + 1) = 2 \)
- **c.** \( \frac{1}{4} \log (6x - 5) = -1 \)

#### Solution approach:
1. Convert each equation to exponential form using \( \log_b (x) = y \Rightarrow x = b^y \).
2. Solve for \( x \).
