Find $\log _{3 / 2} 3.375$

$\frac{\log _{9} 11}{\log _{5} 13}-\frac{\log _{3} 11}{\log _{\sqrt{5}} 13}=$

If $\log _{10}\left[98+\sqrt{x^{2}-12 x+36}\right]=2,$ then $x=$

If $\frac{\log x}{b-c} = \frac{\log y}{c-a} = \frac{\log z}{a-b}$,then $xyz = x^a \cdot y^b \cdot z^c = x^{b+c} \cdot y^{c+a} \cdot z^{a+b} = $

Evaluate: $2 \log _{3} 7 - 7 \log _{3} 2$

If $\log _{x} y=100$ and $\log _{2} x=10,$ then the value of $y$ is
