Answer :

To rewrite [tex]\(\log_7(4x) + \log_7(3y)\)[/tex] as a single logarithm, we can utilize the properties of logarithms. The property that is particularly useful here is the product property of logarithms, which states:

[tex]\[ \log_b(a) + \log_b(c) = \log_b(a \cdot c) \][/tex]

Given this, let's apply the property step by step:

1. Identify the given logarithmic expression:
[tex]\[ \log_7(4x) + \log_7(3y) \][/tex]

2. Use the product property to combine the logarithms:
[tex]\[ \log_7(4x) + \log_7(3y) = \log_7((4x) \cdot (3y)) \][/tex]

3. Simplify the expression inside the logarithm:
[tex]\[ (4x) \cdot (3y) = 4 \cdot 3 \cdot x \cdot y = 12xy \][/tex]

4. Substitute back into the logarithm:
[tex]\[ \log_7((4x) \cdot (3y)) = \log_7(12xy) \][/tex]

Therefore, the expression [tex]\(\log_7(4x) + \log_7(3y)\)[/tex] can be rewritten as a single logarithm:

[tex]\[ \log_7(12xy) \][/tex]
