lg1/4>lg1/5,2>1推出2lg1/4>lg1/5推出lg1/16>lg1/5推出1/16>1/5,以上推理的错
计算:4lg1+lg2.5+lg4-(1/2)lg10^2
(25/16)^(-1/2)+lne^2+C(5,4)-(1-根号7)lg1+sinπ
2lg2+3lg5-lg1除以5
计算log2.5(6.25)+lg1/100+In根号下e+2[1+log2(3)]
(lg根号27+lg5-lg10根号2)/lg1.5
计算 (lg1/2+lg1+lg2+lg4+lg8+.+lg1024)*log2 10
(lg1/4-lg25)除以100的1/2次方等于多少
(lg1/4-lg25)除以100的负1/2次方等于
1.lg1/4-lg25=?
lg16+3lg5-lg1/5的解题步骤及答案,
(lg3+2lg2-1)除以lg1.2=?
计算(lg2/1+lg1+lg2+lg4+...+lg1024)×lg底数2
