diketahui log2=0,3010 log3=0,4771 tentukan nilai dari a.log4 b.log6 c.log9 d.log12

aturan logaritma
• log (a × b) = log a + log b

a) log 4 = log 2 + log 2 = 0,3010 + 0,3010= 0,6020

b) log 6 = log 2 + log 3 = 0,3010 + 0,4771 = 0,7781

c) log 9 = log 3 + log 3 = 0,4771 + 0,4771 = 0,9542

d) log 12 = log 2 + log 2 + log 3
= 0,3010 + 0,3010 + 0,4771
= 1, 0791
