triiiiiiiiiiiiiiii
Sifatnya beserta contoh! 1. ª log a = 1 contoh : ² log 2 = 1 2. ª log 1 = 0 3. ª log aⁿ = n contoh : Nilai dari 2log 84 = …. Jawab: = ²log 8⁴ = 4 x ² log 2³ = 4 x 3 = 12 4. ª log bⁿ = n • ª log b contoh : sederhanakanlah ² log 3 + ⁴ log 3 jawab : ² log 3 + ⁴ log 3 = log 3² + log 3⁴ = log 9 + log 81 = log 9 . 81 = log 729 5. ª log b x log c = ª log c contoh : ³log 7 x ⁷log 81 = ³log 81 = ³log 3⁴ = 4 6. a = x contoh : 5 = 8

Sifat-sifat logaritma : 1) a log 1 = 0 2) a log a = 1 3) a log 1/a = -1 4) a log b + a log c = a log (bxc) 5) a log b - a log c = a log (b/c) 6) a log a^b = b 7) a a log b = b 8) a log b = P log b P log a 9) a c log b^d = d/c x a log b menurut qu y.. klo bngung coment aj..
1. ª log a = 1
contoh : ² log 2 = 1
2. ª log 1 = 0
3. ª log aⁿ = n
contoh : Nilai dari 2log 84 = ….
Jawab: = ²log 8⁴ = 4 x ² log 2³ = 4 x 3 = 12
4. ª log bⁿ = n • ª log b
contoh : sederhanakanlah ² log 3 + ⁴ log 3
jawab : ² log 3 + ⁴ log 3 = log 3² + log 3⁴
= log 9 + log 81
= log 9 . 81
= log 729
5. ª log b x log c = ª log c
contoh : ³log 7 x ⁷log 81 = ³log 81 = ³log 3⁴ = 4
6. a = x
contoh : 5 = 8
1) a log 1 = 0
2) a log a = 1
3) a log 1/a = -1
4) a log b + a log c = a log (bxc)
5) a log b - a log c = a log (b/c)
6) a log a^b = b
7) a a log b = b
8) a log b = P log b
P log a
9) a c log b^d = d/c x a log b
menurut qu y.. klo bngung coment aj..
