Answer :

To solve the expression [tex]\(\log \frac{14}{3} + \log \frac{11}{5} - \log \frac{22}{15}\)[/tex], we can use properties of logarithms to combine these logarithmic terms into a single logarithmic expression.

First, recall the logarithm properties:

1. [tex]\(\log a + \log b = \log (a \times b)\)[/tex]
2. [tex]\(\log a - \log b = \log \left( \frac{a}{b} \right)\)[/tex]

Using these properties, we can simplify the expression step by step.

Starting with:

[tex]\[ \log \frac{14}{3} + \log \frac{11}{5} - \log \frac{22}{15} \][/tex]

Step 1: Combine the sums using the property [tex]\(\log a + \log b = \log (a \times b)\)[/tex]:

[tex]\[ \log \frac{14}{3} + \log \frac{11}{5} = \log \left( \frac{14}{3} \times \frac{11}{5} \right) \][/tex]

Step 2: Simplify the product inside the logarithm:

[tex]\[ \frac{14}{3} \times \frac{11}{5} = \frac{14 \times 11}{3 \times 5} = \frac{154}{15} \][/tex]

Now we have:

[tex]\[ \log \left( \frac{154}{15} \right) - \log \frac{22}{15} \][/tex]

Step 3: Combine the difference using the property [tex]\(\log a - \log b = \log \left( \frac{a}{b} \right)\)[/tex]:

[tex]\[ \log \left( \frac{154}{15} \right) - \log \frac{22}{15} = \log \left( \frac{\frac{154}{15}}{\frac{22}{15}} \right) \][/tex]

Step 4: Simplify the fraction inside the logarithm:

[tex]\[ \frac{\frac{154}{15}}{\frac{22}{15}} = \frac{154}{15} \times \frac{15}{22} = \frac{154 \times 15}{15 \times 22} = \frac{154}{22} = 7 \][/tex]

So, the whole original expression simplifies to:

[tex]\[ \log 7 \][/tex]

Therefore, the correct answer is:

[tex]\[ \log 7 \][/tex]
