Question 1031557
.
logb2=0.43
logb3=0.68
logb7=1.21

Evaluate logb{{{ sqrt( 7/12 ) }}}

answers 
a) -0.505 b)-0.165  c)-0.935 d) none of these  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{log(b,(sqrt(7/12)))}}} = {{{(1/2)*log(b,(7/12))}}} = {{{(1/2)*( log(b,(7)) - log(b,(3)) - log(b,(4)))}}} = {{{(1/2)*(1.21 - 0.68 - 2*0.43)}}}.


Please calculate it yourself and identify the correct option.
