Answer:

Choice 3


log (x^2y)/(z^2)

Explanation:

We use 3 of the rules of logarithms

  • Product Rule :


\log (ab) = \log a + \log b

  • Quotient Rule:


\log(a)/(b) = \log a - \log b

  • Power Rule


\log (a^n) = n\log a


\log(x^2y)/(z^2) =\ log(x^2y) - \log(z^2) (quotient rule)


\log(x^2y) = \log x^2 + \log y (product rule)


\log x^2 = 2\log x (power rule)


\log z^2 = 2\log z (power rule)

Final result


log (x^2y)/(z^2) = 2\log x + \log y - \log z
