<PRE><B>Question 144003</B>
Since {{{log(10,(1))=0}}}, this means that {{{2*log(10,(1))=2*0=0}}}



{{{log(10,(2+3))=log(10,(5))}}}



{{{log(10,(AB^2))=log(10,(A))+log(10,(B^2))=log(10,(A))+2*log(10,(B))}}}




#5 {{{log(10,(1))=0}}} So the characteristic (the integer portion) is 0


#6 {{{log(10,(2520))=3.40140}}} So the characteristic (the integer portion) is 3


#7 {{{log(10,(2.7))=0.43136}}} So the characteristic (the integer portion) is 0


#8 {{{log(10,(0.0045))=-2.34679}}} So the characteristic (the integer portion) is -2</PRE>
