Nilai dari5log 150 – 5log 2 + 5log 8 – 5log 24 =

Jawaban:

LOGARITMA

Hasil dari :

$= {}^{5} log150 - {}^{5} log2 + {}^{5} log8 - {}^{5} log24 \ = {}^{5} log( frac{150}{2} times frac{8}{24} ) \ = {}^{5} log frac{1200}{48} \ = {}^{5} log25 \ = {}^{5} log {5}^{2} \ = 2.( {}^{5} log5) \ = 2.(1) \ = 2$

Konsep yang dipakai :

${}^{a} log : a = 1 \ {}^{a} log : m - {}^{a} log : n = {}^{a} log : frac{m}{n} \ {}^{a} log : m + {}^{a} log : n = {}^{a}log : m times n \ {}^{a} log : m {}^{a} = m.( {}^{a} log : a) = m$
