Use the properties of logarithms to expand [tex]$\log \frac{z}{x^4}$[/tex].

Each logarithm should involve only one variable and should not have any exponents or fractions. Assume that all variables are positive.

[tex]
\log \frac{z}{x^4} =
[/tex]

[tex]
\log z - 4 \log x
[/tex]



Answer :

To expand the expression [tex]\(\log \frac{z}{x^4}\)[/tex] using properties of logarithms, follow these steps:

1. Apply the Logarithm of a Quotient Rule:
The logarithm of a quotient is the logarithm of the numerator minus the logarithm of the denominator. Here, the numerator is [tex]\(z\)[/tex] and the denominator is [tex]\(x^4\)[/tex].
[tex]\[ \log \frac{z}{x^4} = \log(z) - \log(x^4) \][/tex]

2. Apply the Logarithm of a Power Rule:
The logarithm of a power can be expressed as the exponent times the logarithm of the base. Therefore, [tex]\(\log(x^4)\)[/tex] can be written as:
[tex]\[ \log(x^4) = 4 \log(x) \][/tex]

3. Combine the Results:
Substitute the expanded form of [tex]\(\log(x^4)\)[/tex] back into the original equation.
[tex]\[ \log(z) - \log(x^4) = \log(z) - 4 \log(x) \][/tex]

Thus, the expanded form of [tex]\(\log \frac{z}{x^4}\)[/tex] is:
[tex]\[ \log \frac{z}{x^4} = \log(z) - 4 \log(x) \][/tex]
