Jika diketahui log 2=0,3010 dan log 3=0,4771 tentukn logaritma A.log 24 b.log 18 C.log 1,5 d.log 30 e.log 90 f.log 45

A.
Log 24:
= log 4 + log 6
= Log 2 + log 2 + log 2 + log 3
= 0,3010 + 0,3010 + 0,3010 + 0,4771
= 1,3801

B.
Log 18:
= log 9 + log 2
= log 3 + log 3 + log 2
= 0,4771 + 0,4771 + 0,3010
= 1,2552

C.
Log 1,5:
= log 3 - log 2
= 0,4771 - 0,3010
= 0,1761

D.
Log 30:
= log 10 + log 3
= 1 + 0,4771
= 1,4771

E.
Log 90:
= log 9 + log 10
= log 3 + log 3 + log 10
= 0,4771 + 0,4771 + 1
= 1,9542

F.
Log 45:
= log 90 - log 2
= log 3 + log 3 + log 10 - log 2
= 0,4771 + 0,4771 + 1 - 0,3010
= 1,6532
