The value of $\sqrt {(\log _{0.5}^24)} $ is
$-2$
$\sqrt {( - 4)} $
$2$
None of these
(c) $\sqrt {\log _{0.5}^24} = \sqrt {{{\{ {{\log }_{0.5}}{{(0.5)}^{ – 2}}\} }^2}} = \sqrt {{{( – 2)}^2}} = 2$.
If ${\log _{0.04}}(x – 1) \ge {\log _{0.2}}(x – 1)$ then $x$ belongs to the interval
If $log_ab + log_bc + log_ca$ vanishes where $a, b$ and $c$ are positive reals different than unity then the value of $(log_ab)^3 + (log_bc)^3 + (log_ca)^3$ is
If ${a^x} = b,{b^y} = c,{c^z} = a,$ then value of $xyz$ is
The sum $\sum \limits_{n=1}^{\infty} \frac{2 n^2+3 n+4}{(2 n) !}$ is equal to :
If ${\log _{0.3}}(x – 1) < {\log _{0.09}}(x – 1)$ then $x \ne 1$ lies in
