Penjelasan dengan langkah-langkah:
²log(x²-3 / x) = 1
2¹ = (x²-3)/x
2x = x²-3
x²-2x-3 = 0
(x-3)(x+1)=0
x-3 = 0, x = 3
x+1 = 0, x = -1
x = {3, -1}
Mungkin jawaban hanya 3 karena log tdk bisa negatif tapi dalam hal ini, jika negatif masih bisa dikerjakan.
²log((-1)²-3) - log(-1)
²log(-2) - log(-1)
²log(-2/-1)
²log(2)
1
