Question - Logarithm Equivalence Proof

Given \(\log\frac{81}{8} = 2\log\frac{2}{3} + 3\log\frac{1}{3}\)

Apply logarithm properties: \(\log a^b = b \cdot \log a\)

\(\log\frac{3^4}{2^3} = \log\left(\frac{2}{3}\right)^2 + \log\left(\frac{1}{3}\right)^3\)

\(\log\frac{3^4}{2^3} = \log\left(\frac{2^2}{3^2}\right) + \log\left(\frac{1}{3^3}\right)\)

\(\log\frac{3^4}{2^3} = \log\frac{2^2}{3^2} + \log\frac{1}{3^3}\)

\(\log\frac{3^4}{2^3} = \log\frac{2^2}{3^2} + \log\frac{1}{3^3}\)

Combine logs on the right using \(\log a + \log b = \log(ab)\):

\(\log\frac{3^4}{2^3} = \log\left(\frac{2^2}{3^2} \cdot \frac{1}{3^3}\right)\)

\(\log\frac{3^4}{2^3} = \log\frac{2^2}{3^5}\)

Simplify the right side:

\(\log\frac{3^4}{2^3} = \log\frac{3^4}{2^3}\)

Since the logs with the same base are equal, their arguments must be equal, proving the statement:

\(\frac{3^4}{2^3} = \frac{3^4}{2^3}\)

Hence, the given equation is proved to be correct.
