tolong di jawab yah butuh kali jawaban nya

jawab
logaritma
a'log b+ a'log c = a'log bc
a'log b - a'log c = a'log b/c

1. ³log 405 + ³log 1/5 = ³log ( 405 . 1/5) = ³log 81= ³log 3⁴ = 4

2. ⁵log 500 - ⁵log 4 = ⁵log (500/4) = ⁵log 125= ⁵log 5³ = 3

3. ²log 4 + ²log 12 - ²log 6 = ²log (4.12 / 6) = ²log 8 = ²log 2³ = 3
