6log (x2 –16) –6log (2x –7)> 2 – 6log 9

We are tasked with solving the inequality:

\[
6 \log(x^2 - 16) - 6 \log(2x - 7) > 2 - 6 \log 9
\]

### Step 1: Simplify the logarithmic terms
Factor out the common term of \( 6 \) from both sides of the inequality:

\[
6[\log(x^2 - 16) - \log(2x - 7)] > 2 - 6 \log 9
\]

### Step 2: Apply the properties of logarithms
Use the property of logarithms that states \( \log a - \log b = \log \left(\frac{a}{b}\) to simplify the left side:

\[
6 \log\left(\frac{x^2 - 16}{2x - 7}\right) > 2 - 6 \log 9
\]

### Step 3: Divide both sides by 6
To simplify the inequality, divide both sides by 6:

\[
\log\left(\frac{x^2 - 16}{2x - 7}\right) > \frac{2}{6} - \log 9
\]

This simplifies to:

\[
\log\left(\frac{x^2 - 16}{2x - 7}\right) > \frac{1}{3} - \log 9
\]

Since \( \log 9 \) can be rewritten as \( \log 3^2 = 2 \log 3 \), the inequality becomes:

\[
\log\left(\frac{x^2 - 16}{2x - 7}\right) > \frac{1}{3} - 2 \log 3
\]

### Step 4: Express the inequality in exponential form
First, rewrite the term \( x^2 - 16 \) as \( (x - 4)(x + 4) \):

\[
\log\left(\frac{(x - 4)(x + 4)}{2x - 7}\right) > \frac{1}{3} - 2 \log 3
\]

From here, it is possible to solve for \( x \) by expressing both sides in exponential form.
