lg1.2怎么化简成lg3+2lg2-1
(lg3+2lg2-1)除以lg1.2=?
计算(lg2/1+lg1+lg2+lg4+...+lg1024)×lg底数2
(lg3/2lg2+lg3/3lg2)*(lg2/lg3+lg2/2lg3)
(lg3分之2lg2+lg3分之3lg2)(lg2分之lg3+lg2分之2lg3)
1/(1+log3 2)+1/(1+log2 3)=lg3/(lg2+lg3)+lg2/(lg2+lg3)=1解释一下这
lg1 lg2 lg3 lg4 .lg9等于多少
(lg1+lg2+lg3+lg4+lg8+``````+lg1024)
计算 (2lg2+lg3)/(1+lg0.6+lg2)
急(lg根号下27+lg8-lg根号下1000)\lg1.2=(3/2lg3+3lg2-3/2)/lg1.2然后呢
计算:4lg1+lg2.5+lg4-(1/2)lg10^2
计算 (lg1/2+lg1+lg2+lg4+lg8+.+lg1024)*log2 10
(lg3(lg2+lg5)/lg2lg5) *[ lg5(lg3+lg9)/lg3lg9]*lg2=(lg3+2lg3)
