જો $a = {\log _{24}}12,\,b = {\log _{36}}24$ અને $c = {\log _{48}}36$ તો $1+abc = . . . .$
$2ab$
$2ac$
$2bc$
$0$
$(0.16)^{\log _{2.5}\left(\frac{1}{3}+\frac{1}{3^{2}}+\frac{1}{3^{3}}+\ldots . to \infty\right)}$ ની કિમત શોધો
${\log _4}18 = . . . .$
જો ${\log _e}\left( {{{a + b} \over 2}} \right) = {1 \over 2}({\log _e}a + {\log _e}b)$, તો $a$ અને $b$ વચ્ચેનો સંબંધ મેળવો.
${81^{(1/{{\log }_5}3)}} + {27^{{{\log }_{_9}}36}} + {3^{4/{{\log }_{_7}}9}} = . . . .$
${\log _3}\,4{\log _4}\,5{\log _5}\,6{\log _6}\,7{\log _7}\,8{\log _8}\,9= . .$ . .
