If ${\log _{0.04}}(x - 1) \ge {\log _{0.2}}(x - 1)$ then $x$ belongs to the interval
$\left( {1,\,\,2} \right]$
$\left( { - \infty ,\,2} \right]$
$\left[ {2, + \,\infty } \right)$
None of these
The solution of the equation ${\log _7}{\log _5}$ $(\sqrt {{x^2} + 5 + x} ) = 0$
$\sum\limits_{r = 1}^{89} {{{\log }_3}(\tan \,\,{r^o})} = $
If $x = {\log _5}(1000)$ and $y = {\log _7}(2058)$ then
The number of solution of ${\log _2}(x + 5) = 6 - x$ is
