Use the properties of logarithms to expand logz4x.Each logarithm should involve only one variable and should not have any exponents. Assume that all variables are positive.

The Solution:
Given:
We are required to use the logarithm property to find an equivalent for the given expression.
By logarithm Property:
[tex]log\frac{z^4}{x}=logz^4-logx=4logz-logx[/tex]Therefore, the correct answer is:
[tex]4logz-logx[/tex]
