If ${1 \over {{{\log }_3}\pi }} + {1 \over {{{\log }_4}\pi }} > x,$ then $x$ be
$2$
$3$
$3.5$
$\pi $
If ${\log _{0.3}}(x - 1) < {\log _{0.09}}(x - 1),$ then $x$ lies in the interval
If ${a^2} + 4{b^2} = 12ab,$ then $\log (a + 2b)$ is
If $x = {\log _b}a,\,\,y = {\log _c}b,\,\,\,z = {\log _a}c$, then $xyz$ is
If $x = {\log _3}5,\,\,\,y = {\log _{17}}25,$ which one of the following is correct
If ${\log _5}a.{\log _a}x = 2,$then $x$ is equal to
