Question 1023936
{{{ 3*log(4) + 3*log(2) + log(7) - 3*log(7) }}}
{{{ log( 4^3 ) + log( 2^3 ) + ( 1 - 3 )*log( 7 ) }}}
{{{ log( 4^3 ) + log( 2^3 ) - 2*log( 7 ) }}}
{{{ log( 4^3 ) + log( 2^3 ) - log( 7^2 ) }}}
{{{ log(( 4^3*2^3 / 7^2 )) }}}
{{{ log(( 512 / 49 )) }}}
---------------------
check answer:
{{{ log(4) = .60206 }}}
{{{ log(2) = .30103 }}}
{{{ log(7) = .8451 }}}
--------------------
{{{ 3*log(4) + 3*log(2) + log(7) - 3*log(7) }}}
{{{ 3*.60206 + 3*.30103 + .8451 - 3*.8451 }}}
{{{ 1.80618 + .90309 + .8451 - 2.5353 }}}
{{{ 3.55437 - 2.5353 = 1.01907 }}}
and
{{{ 512/49 = 10.44897 }}}
{{{ log( 10.44897 ) = 1.01907 }}}
OK
