Combine the logarithms:

[tex]\[
\log_8 5 + \log_8 7 = \log_8 \square
\][/tex]

Use the logarithm property: [tex]\(\log_b a + \log_b c = \log_b (a \cdot c)\)[/tex]

[tex]\[
\log_8 (5 \cdot 7) = \log_8 35
\][/tex]



Answer :

Certainly! To solve the logarithmic expression [tex]\(\log_8 5 + \log_8 7 = \log_8 \square\)[/tex], we can use the properties of logarithms. Here’s a detailed step-by-step explanation:

1. Recall the Property of Logarithms:
One of the key properties of logarithms is that the sum of two logarithms with the same base can be combined into a single logarithm. Specifically:
[tex]\[ \log_b(a) + \log_b(c) = \log_b(a \cdot c) \][/tex]
This property is often referred to as the logarithm multiplication property.

2. Apply the Property:
Using the property above, we can combine the two logarithms in our expression:
[tex]\[ \log_8 5 + \log_8 7 = \log_8 (5 \cdot 7) \][/tex]

3. Perform the Multiplication:
Next, we need to multiply the numbers inside the logarithm:
[tex]\[ 5 \times 7 = 35 \][/tex]

4. Combine the Results:
So, the expression [tex]\(\log_8 (5 \cdot 7)\)[/tex] simplifies to:
[tex]\[ \log_8 (35) \][/tex]

Therefore, the value inside the logarithm that completes the equation [tex]\(\log_8 5 + \log_8 7 = \log_8 \square\)[/tex] is [tex]\(35\)[/tex]. Hence, the completed equation is:

[tex]\[ \log_8 5 + \log_8 7 = \log_8 35 \][/tex]

So, [tex]\(\square = 35\)[/tex].
