^3 log 12 + ^3 log 4 - 2× ^2 log 4/3

'3 log 12 + '3 log 4 - 2× '2 log 4/3
= '3 log 12 + '3 log 4 - '2 log( 4/3)^2
='3 log 12 + '3 log 4 - '2 log 16/9
='3 log( 12 x 4) - ( '2 log 16- '2 log9
='3 log 48 - ( '2 log (2^4) - '2 log9)
= '3 log 48 - '2 log (2^4) + '2 log9
='3 log 48 - 4 x '2 log2 + '2 log9
= log 48 / log 3 + log 9 / log 2 - 4
