Pembahasan :
²log 4 = ²log 2²
²log 4 = 2 . ²log 2
²log 4 = 2 . 1
²log 4 = 2

a) 2log4 = 2log2^2 = 2 . 2log2 = 2 . 1 = 2
b) 4log64 = 4log4^3 = 3 . 4log4 = 3 . 1 = 3
c) 36log216 = (6^2)log6^3 = 3/2 . 6log6 = 3/2
d) log 0,00001 = log 10^-5 = -5 . log 10 = -5
e) 3log(1/9) . (1/4)log256 = 3log3^-2 . (4^-1)log4^4
= -2 . 3log3 . 4/(-1) . 4log4
= -2 . -4
= 8
