9log27 - 4log1/2 + 16log8 = Pakai cara ya ~

jawabannya 11/4 ,, caranya silahkan lihat gambar,,

9log 27 = log 27/log 9 = log 3^3/log 3^2 = 3.log 3/ 2.log 3 = 3/2
4log 1/2 = log (1/2)/ log 4 = log 2^-1/log 2^2
= -1.log 2 / 2.log 2 = -1/2
16log 8 = log 8/log 16 = log 2^3/log 2^4 = 3.log 2 / 4.log 2 = 3/4
=> 3/2 - - 1/2 + 3/4
=> 3/2 + 1/2 + 3/4
=> 4/2 + 3/4
=> 2 3/4
