Which of the following is equivalent to [tex]\log 9w[/tex]?

A. [tex]\log 9 + \log w[/tex]

B. [tex]\log 9 - \log w[/tex]

C. [tex]w(\log 9)[/tex]

D. [tex]9(\log w)[/tex]



Answer :

To determine which expression is equivalent to [tex]\(\log 9w\)[/tex], we use the logarithmic property which states that the logarithm of a product is the sum of the logarithms of the factors.

The property is:
[tex]\[ \log(ab) = \log(a) + \log(b) \][/tex]

In this case, we have [tex]\(\log(9w)\)[/tex]. Here, [tex]\(a = 9\)[/tex] and [tex]\(b = w\)[/tex].

Applying the property, we get:
[tex]\[ \log(9w) = \log(9) + \log(w) \][/tex]

So, the correct equivalent expression to [tex]\(\log(9w)\)[/tex] is:
[tex]\[ \log 9 + \log w \][/tex]

Hence, the correct answer is:
[tex]\[ \boxed{\log 9 + \log w} \][/tex]
