Which of these expressions is equivalent to log (3 8)? A. log (3) – log (8) B. log (3) + log (8) C. log (3) log (8) D. 3 log (8)

Respuesta :

I'm pretty sure they're trying to say (3*8). For APEX the answer is log (3) + log (8)

Answer: The correct option is (A) [tex]\log(3)-\log(8).[/tex]

Step-by-step explanation:  We are to select the correct expression that is equivalent to the following logarithmic expression:

[tex]E=\log\left(\dfrac{3}{8}\right).[/tex]

We have the following property of logarithm:

[tex]\log\left(\dfrac{a}{b}\right)=\log a-\log b.[/tex]

Therefore, we have

[tex]E\\\\\\=\log\left(\dfrac{3}{8}\right)\\\\\\=\log (3)-\log (8).[/tex]

Thus, the given expression is equivalent to [tex]\log(3)-\log(8).[/tex]

Option (A) is correct.
