nilai dari 2log 27- 2log 20- 2log 2/5+ 5log 625 adalah

²log 27-²log 20-²log 2/5 + ^5log625
= (²log 27-²log 20) - ²log 2/5 + ^5log5⁴
= (²log(27/20)) - ²log 2/5 + 4
= ²log(27/20) - ²log 2/5 + 4
*note: 4 = ²log2⁴ = ²log16
lanjut....
= ²log(27/20) -²log 2/5 + ²log16
= ²log(27/20) + ²log(16÷2/5)
=²log(27/20) + ²log(16×5/2)
= ²log(27/20) + ²log 40
= ²log(27/20 × 40)
= ²log 54
semoga membantuuu!!
