Question

Nilai X yang memenuhi 3 log 9/2 + 3 log 4 - 3 log x=1 adalah

Answer 1

Alog b + alog c = alog b × c
alog b - alog c = alog b/c
alog a = 1

3log 9/2 + 3log 4 - 3log x = 1
3log(9/2 × 4/x) = 3log3 (3log habis)
9/2 × 4/x = 3
9 × 2/x = 3
18/x = 3 (kali silang)
18 = 3x
x = 18/3 = 6

maaf kalau salah
semoga membantu
