Question 687625
Is this correct:
{{{ log( 3, ( 3*sqrt(x/81) )) }}} ?, if so
{{{ log( 3,3 ) + log( 3, (x/81)^(1/2) ) }}}
{{{ 1 + (1/2)*log( 3,(x/81) ) }}}
{{{ 1 + (1/2)*( log( 3, x )  - log( 3,81 ) ) }}}
{{{ 1 + (1/2)*( log( 3,x ) - 4 ) }}}
{{{ (1/2)*log( 3, x ) - 2 + 1 }}}
{{{ (1/2)*log( 3,x ) - 1 }}} answer
check:
{{{ log( 3, ( 3*sqrt(x/81) )) = ( 1/2 )*log( 3,x ) - 1 }}}
Multiply both sides by {{{ 2 }}}
{{{ 2*log( 3, ( 3*sqrt(x/81) )) = log( 3,x ) - 2 }}}
{{{ log( 3, 9*(x/81) ) = log( 3,x ) - 2 }}}
{{{ log( 3, x/9 ) = log( 3,x ) - 2 }}}
{{{ log( 3,x ) - log( 3,9 ) = log( 3,x ) - 2 }}}
{{{ log( 3,x ) - 2 = log( 3,x ) - 2 }}}
OK
Unless I goofed- check it carefully
