lg32+log4 16+6lg1/2+lg1/5=
[(lg2+lg5-lg1)/(2lg0.5+lg8)]*(lg32-lg2) 分步计算步骤,
lg2+lg5-lg1/2lg+lg8 x (lg32-lg2)过程与答案
2lg2+3lg5-lg1除以5
设f(x)=lg1+2
lg2=0.3010求lg1/2
计算 (lg1/2+lg1+lg2+lg4+lg8+.+lg1024)*log2 10
1.lg1/4-lg25=?
(25/16)^(-1/2)+lne^2+C(5,4)-(1-根号7)lg1+sinπ
计算:4lg1+lg2.5+lg4-(1/2)lg10^2
27^(2/3)+2lg1+lg25+lg4=
(lg3+2lg2-1)除以lg1.2=?
(lg根号27+lg5-lg10根号2)/lg1.5
