Solution

The image contains a logarithmic problem involving simplifications. Here's a step-by-step breakdown of the parts visible:

Equation:

The main expression involves several logarithmic terms. It seems to involve: 3log243log(23)+3log(819)3 \log 24 - 3 \log (2 \sqrt{3}) + 3 \log \left(\frac{81}{9}\right)

Step-by-Step Breakdown:

  1. First term: 3log243 \log 24 This can remain as it is for now, though further simplification could involve breaking 24 down into prime factors.

  2. Second term: 3log(23)-3 \log (2 \sqrt{3}) Using logarithmic properties, we can split the logarithm: 3log(23)=3log2+3log3=3log2+32log33 \log (2 \sqrt{3}) = 3 \log 2 + 3 \log \sqrt{3} = 3 \log 2 + \frac{3}{2} \log 3

  3. Third term: 3log(819)3 \log \left(\frac{81}{9}\right) This simplifies using the property log(ab)=logalogb\log \left(\frac{a}{b}\right) = \log a - \log b: 3log(819)=3(log81log9)3 \log \left(\frac{81}{9}\right) = 3 (\log 81 - \log 9) log81=log(34)=4log3andlog9=log(32)=2log3\log 81 = \log (3^4) = 4 \log 3 \quad \text{and} \quad \log 9 = \log (3^2) = 2 \log 3 So, we have: 3(4log32log3)=3(2log3)=6log33 (4 \log 3 - 2 \log 3) = 3 (2 \log 3) = 6 \log 3

Combined expression:

Now, combining all terms: 3log24(3log2+32log3)+6log33 \log 24 - (3 \log 2 + \frac{3}{2} \log 3) + 6 \log 3 This simplifies further as: 3log243log232log3+6log33 \log 24 - 3 \log 2 - \frac{3}{2} \log 3 + 6 \log 3 =3(log24log2)+(6log332log3)= 3 (\log 24 - \log 2) + (6 \log 3 - \frac{3}{2} \log 3) =3log12+(92log3)= 3 \log 12 + \left(\frac{9}{2} \log 3\right)

The final simplified form is: 3log12+92log33 \log 12 + \frac{9}{2} \log 3
