Math Problem Statement

Solve

Solve the expression involving logarithms in the image.

Solution

The expression shown in the image is:

5log16x2log3,9log55 \log 16 \cdot x^{2 \log \sqrt{3}}, 9 \log 5

Simplifying the components:

  1. First part: 5log16x2log35 \log 16 \cdot x^{2 \log \sqrt{3}}

    • 5log165 \log 16 is a constant multiplication term. We know that log16=log(24)=4log2\log 16 = \log (2^4) = 4 \log 2. Thus: 5log16=54log2=20log25 \log 16 = 5 \cdot 4 \log 2 = 20 \log 2
    • Now, simplify x2log3x^{2 \log \sqrt{3}}. Since 3=31/2\sqrt{3} = 3^{1/2}, we can express log3=12log3\log \sqrt{3} = \frac{1}{2} \log 3. Therefore: x2log3=x212log3=xlog3x^{2 \log \sqrt{3}} = x^{2 \cdot \frac{1}{2} \log 3} = x^{\log 3} Using the logarithmic property xloga=alogxx^{\log a} = a^{\log x}, we can simplify: xlog3=3logxx^{\log 3} = 3^{\log x}

    Hence, the entire first part simplifies to: 20log23logx20 \log 2 \cdot 3^{\log x}

  2. Second part: 9log59 \log 5

    This is simply: 9log59 \log 5

Thus, the simplified form of the expression is:

20log23logx,9log520 \log 2 \cdot 3^{\log x}, 9 \log 5
