Dados log 3= 0,48 e log 5= 0,70 calcule:
Log 75=
Log 15 * 5 = 
Log15 + Log 5 = 
Log3*5 + Log5 = 
Log3 + Log5 + Log5 = 
1,88

Dados log 2= a e log 3= b calcule:
Log 12/6 = 
Log12 - Log6 =
Log 2*6 - Log 2*3 = 
Log 2 + Log6 - Log2 + Log3 = 
Log2 + Log2 + Log3 - Log2 + Log3 = 
Log2 + Log3 + Log3 = 
a + b + b = 
a + 2b
