selamat pagi... tolong di jwabkan dong kak.Udah mau di kumpul.

1. log 4/8 + log 150/3 = log ½ + log 50 = log (½×50) = log 25 = log 5² = 2 log 5

2. MN akan berordo 3×2

3. 2-6x=-10
-6x=-12
x=2

5. b = 22-6/10-2 = 16/8 = 2
U2 = a+(2-1)2
6 = a+(1)2
6 = a+ 2
a = 4
Sn = n/2(2a+(n-1)b)
S20 = 20/2(2.4+(20-1)2)
S20 = 10(8+(19)2)
S20 = 10(8+38)
S20 = 10(46)
S20 = 460

Semoga bermanfaat .. Itu kalo saya gak salah hitung, kalo salah hapus saja ..
