Question

Diketahui log2 = 0,301; log3 = 0,477; dan log5 =0,699 tentukan nilai dari :

a. log 0,6
b. log 20
c. log 90

Answer 1

A. Log 0,6 = log (2:3) =log 2 - log 3= 0,301 - 0, 477 = -0,176 b. Log 20 = log (2.5.2) = log 2 + log 5 +log 2 = 0,301 + 0,699 + 0.301=1,301 c. Log 90 = log (3.3.5.2) = log3+ log3 + log5 + log2 =0,477+0,477+0,699+0,301 =1,954
