1. Jawaban hr71
A. log (( 3 . 4 . 5/3 )/2)= log 10 = 1
B. 5 ²log 2 - (-6) ²log 2 = 5+6 = 11 -
2. Jawaban ArZain
A). log 3 + log 4 + log 5/3 - log 2
= log(3.4) + log 5/3 - log 2
= log 12 + log 5/3 - log 2
= log(12.5/3) - log 2
= log 20 - log 2
= log(20:2)
= log 10
= 1
B). ²log 32 - ²log 1/64
= ²log(32:1/64)
= ²log(32.64/1)
= ²log 2048
= ²log 2¹¹
= 11.²log 2
= 11.1
= 11
