= 2(log 15 - log 18 ) - 2log 5 + log162 + 2(log 2 - log 3 )
= 2 log(3x5) - 2log(2x9) - 2log5 + log(9^2x2) + 2log2 - 2log3
= 2log3 + 2log5 -2log2 - 2log9 -2log5 + 2log9 + log2 + 2log2 -2log3
= log2
= 2 log(3x5) - 2log(2x9) - 2log5 + log(9^2x2) + 2log2 - 2log3
= 2log3 + 2log5 -2log2 - 2log9 -2log5 + 2log9 + log2 + 2log2 -2log3
= log2
