(lg3+2lg2-1)除以lg1.2=?
(lg3+2lg2-1)除以lg1.2=?
急(lg根号下27+lg8-lg根号下1000)\lg1.2=(3/2lg3+3lg2-3/2)/lg1.2然后呢
2lg2+3lg5-lg1除以5
1/(1+log3 2)+1/(1+log2 3)=lg3/(lg2+lg3)+lg2/(lg2+lg3)=1解释一下这
计算 (2lg2+lg3)/(1+lg0.6+lg2)
2lg2+lg3除以2+lg0.36+2lg2
(lg3(lg2+lg5)/lg2lg5) *[ lg5(lg3+lg9)/lg3lg9]*lg2=(lg3+2lg3)
(2lg5·2lg2·2lg3)/(lg5·lg2·lg3)=
lg2=0.3010求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)
