2³log² x - ³log x³ + log 10 = 0
2³log² x - 3³log x = - (log 10)
³log x (2³log x - 3) = - (log 10)

x1
³log x = - (log 10)
³log x = -1
3^-1 = x
x = 1/3

x2
2³log x - 3 = - (log 10)
2³log x = -1 + 3
2³log x = 2
³log x = 1
3^1 = x
x = 3         
terima kasih
itu dapat ³log x (2³log x - 3) dari mana ya kak,terima kasih
