Hp dari 3log^2 2x+3log8x+3log9=0

Logaritma

Mungkin maksud soal spt ini :
³log² 2x + ³log 8x³ + ³log 9 = 0

³log² 2x + ³log (2x)³ + ³log 3² = 0
³log² 2x + 3 . ³log 2x + 2 = 0
(³log 2x + 1)(³log 2x + 2) = 0

³log 2x + 1 = 0
³log 2x = -1
2x = 3^-1 = 1/3
x = 1/6 

³log 2x + 2 = 0
³log 2x = -2
2x = 3^-2 = 1/3²
x = 1/18

HP = {1/6 , 1/18}
