24. [tex]\(\log \left(\frac{1}{n}\right) =\)[/tex]

(a) [tex]\(\log 1\)[/tex]

(b) [tex]\(\log n\)[/tex]

(c) [tex]\(\log (1 - n)\)[/tex]

(d) [tex]\(-\log n\)[/tex]



Answer :

Certainly! Let's analyze the logarithmic expression [tex]\(\log \left(\frac{1}{n}\right)\)[/tex].

We can use the properties of logarithms to simplify this expression. One important property of logarithms that is useful here is:

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

In this case, we can apply this property with [tex]\(a = 1\)[/tex] and [tex]\(b = n\)[/tex]:

[tex]\[ \log \left(\frac{1}{n}\right) = \log 1 - \log n \][/tex]

Next, we need to evaluate [tex]\(\log 1\)[/tex]. It is a well-known fact that the logarithm of 1 in any base is always 0:

[tex]\[ \log 1 = 0 \][/tex]

So we substitute [tex]\(\log 1\)[/tex] with 0 in the expression:

[tex]\[ \log \left(\frac{1}{n}\right) = 0 - \log n \][/tex]

Simplifying this, we get:

[tex]\[ \log \left(\frac{1}{n}\right) = -\log n \][/tex]

Therefore, the correct answer is:

[tex]\[ \boxed{-\log n} \][/tex]

So the answer to the question is option (d) [tex]\(-\log n\)[/tex].
