If $\log_{10} 2 = 0.3010$,then $\log_{10}(1/2) =$

If $\log _{a} b=\log _{b} c=\log _{c} a$,then:

If $\log _{8} p=2.5$ and $\log _{2} q=5$,then $p$ in terms of $q$ is

If $x = \log_{4/3}(1/2)$ and $y = \log_{1/2}(1/3)$,then

If $\log 2=x, \log 3=y$ and $\log 7=z,$ then the value of $\log (4 \sqrt[3]{63})$ is

If $\frac{\log x}{a^{2}+a b+b^{2}}=\frac{\log y}{b^{2}+b c+c^{2}}=\frac{\log z}{c^{2}+c a+a^{2}}$,then $x^{a-b} \cdot y^{b-c} \cdot z^{c-a}=$
