Use the properties of logarithms to condense the expression

1/3[ln(x - 6)- 4 ln y - 2 ln z]

ln [(x-6)/(y^4z^2)]^1/3

To condense the expression using the properties of logarithms, we can apply the following rules:

1. Product rule: log_a(b) + log_a(c) = log_a(b * c)
2. Quotient rule: log_a(b) - log_a(c) = log_a(b / c)
3. Power rule: log_a(b^c) = c * log_a(b)

Let's apply these rules step by step to condense the expression:

1/3[ln(x - 6)- 4 ln y - 2 ln z]

First, we can use the power rule to simplify the coefficients of the logarithms:

1/3[ln(x - 6) + ln(y^(-4)) + ln(z^(-2))]

Next, we can use the product rule to combine the three logarithms into a single logarithm:

1/3[ln((x - 6) * y^(-4) * z^(-2))]

Then, we can simplify further by applying the power rule to each term inside the logarithm:

1/3[ln((x - 6) / (y^4 * z^2))]

Finally, we can remove the brackets to obtain the condensed form:

ln((x - 6) / (y^4 * z^2)) / 3

Therefore, the condensed form of the expression is ln((x - 6) / (y^4 * z^2)) / 3.
