a) log 72
b) log 40,5
tolong bantuannya 🙂
Diket log 2 = 0,3010 , log 3 = 0,4771 . tentukan :
Diket 2log =0,3010, log 3=0.4771
a) log 72= log(3x3x3)
= log 3 + log 3 + log 3
= 0.4771 + 0.4771 +0.4771 = 1,4313
b) lo 40,5 = log (3x3x3x3:2)
= log 3 + log 3 +log 3 + log 3 – log 2
= 0.4771 + 0.4771 +0.4771 +0.4771 – 0,3010
= 1,1303
ini jawaban nya maaf kalau salah
