Question

Contract the expression into a single logarithm with coefficient of 1. Simply completely. 

The mathematical expression is:

\[ 6 \log(x^2 - 81) - 12 \left[ \log(x + 9) - 3 \log(x) \right] \]

This expression involves logarithmic functions, which are commonly used in algebra to solve equations involving exponentials. The expression breaks down as a combination of logarithms with different arguments and coefficients, utilizing properties such as the log of a product, quotient, and powers. The specific terms are:

- \( 6 \log(x^2 - 81) \): This term represents six times the logarithm of \( x^2 \) minus 81.
- \( -12 \left[ \log(x + 9) - 3 \log(x) \right] \): This portion begins with a multiplication of -12 and involves the subtraction of \( \log(x+9) \) and three times \( \log(x) \).

Understanding how to manipulate and simplify such expressions is essential in solving complex logarithmic equations in higher-level mathematics.
