Question

Log 2 = 0,3010
log 3 = 0,4771
log 5 = 0,6990
tentukan :
a. log 2000
b. log 0,00003
c. log 2√3

Answer 1

A. log 2000 = log (2*1000) = log 2 + log 1000 = 0.3010+3=3,3010
b. log 0,00003 = log (3*10^-5)= log 3 + log (10^-5) = 0,4771 + (-5)=(-4,5229)
c. log 2√3 = log2 + log 3^(1/2) =0,3010 + (1/2) 0,4771=0,3010+0,23855=0,53955
