Penjelasan dengan langkah-langkah:

Sifat2 logaritma

alog a = 1 => ² log 2 = 1

Perhatikan contoh diatas, jika logaritma dari kedua bilangan bernilai sama maka hasilnya adalah 1

Contoh lainnya ⁵log5 = 1

alog 1 = 0 => ⁵log 1 = 0

an log bm = m/n alog b, di mana n ≠ 0

⁵³log 7² => 2/3 ⁵log7

alog b = 1/ blog a => ²log3 = 1/³log2

alog b = plog b/plog a , di mana p > 0, p ≠ 1

5log3 = log 3/log 5

a alogb = b ( a pangkat alogb)

4⁴log5 (4pangkat ⁴log5) = 5

alog b x blog c = alog c

²log 3 x ³log 4 x ⁴log 5 = ²log 5

alog bc = alog b + a log c

²log (3.5) = ²log 3 + ²log 5

alog b/c = alog b – alog c

²log (3/5) = ²log 3 – ²log 5

Contoh

⁵log 100 – ⁵log 4 = ⁵log (100/4) = ⁵log 25 = ⁵log 5² = 2
