Jawaban:
X=3
Penjelasan dengan langkah-langkah:
Logaritma
a log b = n → aⁿ = b
a log aⁿ = n
a log b + a log c = a log (b . c)
maka:
³log (x) + ³log (9) = 3
³log (x) + ³log (3)² = 3
³log (x) + 2 = 3
³log (x) = 3 - 2
³log (x) = 1
3¹ = x
x = 3
Jadi, nilai x yang memenuhi adalah 3.
Pembuktian
³log (3) + ³log (3)² = 3
1 + 2 = 3
3 = 3 → Terbukti
