1. Jawaban mhaidarfh02
a. Log 20 = log 2.10 = log 2 + log 10 = 0,3010 + 1 = 1,3010
b. Log 30 = log 3.10 = log 3 + log 10 = 0,4771 + 1 = 1,4771
c. Log 60 = log 2.3.10 = log 2 + log 3 + log 10 = 0,3010 + 0, 4771 + 1 = 1,7781
d. Log 3√2 = log 3. + log √2 = log 3 + 1/2. log 2 = 0,4771 + 1/2 . 0,3010 = 0,6276
