Solution

The equation in the image is:

log372+log33log37\log_3{72} + \log_3{3} - \log_3{7}

Let's solve this step by step:

Step 1: Apply the logarithm properties

  1. Sum of logarithms: logab+logac=loga(b×c)\log_a{b} + \log_a{c} = \log_a{(b \times c)}
  2. Difference of logarithms: logablogac=loga(bc)\log_a{b} - \log_a{c} = \log_a{\left(\frac{b}{c}\right)}

So, we can rewrite the expression:

log372+log33log37=log3(72×3)log37\log_3{72} + \log_3{3} - \log_3{7} = \log_3{\left(72 \times 3\right)} - \log_3{7}

=log3(72×37)= \log_3{\left(\frac{72 \times 3}{7}\right)}

Step 2: Simplify the expression inside the logarithm

Calculate the value inside the logarithm:

72×3=21672 \times 3 = 216

Now, divide by 7:

216730.857\frac{216}{7} \approx 30.857

Thus, the expression simplifies to:

log330.857\log_3{30.857}

Step 3: Final Answer

The final expression is:

log330.857\log_3{30.857}

This is the exact expression, but if you want to approximate the numerical value:

log330.8573.091\log_3{30.857} \approx 3.091
