12. Nilai dari \( \frac{{ }^{2} \log 3 .{ }^{5} \log 32 .{ }^{3} \log 5}{{ }^{5} \log \frac{1}{25}} \) adalah .... A. \( -\frac{5}{2} \) B. \( \frac{32}{25} \) C. \( -\frac{5}{25} \) D. \( \frac{5}{2} \) E. \( -\frac{2}{5} \)

What function is the reflection of \( f(x)=|x+2| \) about the \( x \)-axis? \( g(x)=|x-2| \) Non of the other options \( g(x)=|-x+2| \) \( g(x)=-|x-2| \)

Simplify the logarithmic expression: \( \text{\log}_{2}(8) + \text{\log}_{2}(4) \)

30. List the first five terms of the sequence defined recursively by \( a_{n}=\frac{a_{n-1}}{2}+2 ; a_{1}=68 \)

Find the domain and range of \( y=\log _{2}(8-4 x) \).

Which of the following is equivalent to \( \log \left(\frac{1}{x y}\right) \) ? (1 point) \( 1-\log x-\log y \) \( \log x-\log y \) \( -\log x-\log y \) \( -\log x+\log y \)
