Math Problem Statement

Condense the logarithmic expression: log₃ 6 + 2·log₃ x + 1/2 log₃ 9

Solution

To condense the given logarithmic expression, we'll use the following logarithmic rules:

  1. Product Rule: logb(m)+logb(n)=logb(mn)\log_b(m) + \log_b(n) = \log_b(m \cdot n)
  2. Power Rule: clogb(m)=logb(mc)c \cdot \log_b(m) = \log_b(m^c)

The expression is: log36+2log3x+12log39\log_3 6 + 2 \cdot \log_3 x + \frac{1}{2} \log_3 9

Step 1: Apply the Power Rule

  1. 2log3x=log3(x2)2 \cdot \log_3 x = \log_3 (x^2)
  2. 12log39=log3(912)=log33\frac{1}{2} \log_3 9 = \log_3 (9^{\frac{1}{2}}) = \log_3 3 (since 91/2=39^{1/2} = 3)

Now the expression becomes: log36+log3(x2)+log33\log_3 6 + \log_3 (x^2) + \log_3 3

Step 2: Apply the Product Rule

Combine all the logarithmic terms: log3(6x23)\log_3 (6 \cdot x^2 \cdot 3)

Step 3: Simplify the Expression

Multiply inside the logarithm: log3(18x2)\log_3 (18x^2)

So, the condensed form of the logarithmic expression is: log3(18x2)\boxed{\log_3 (18x^2)}
