lg^32+lg^35+3log2*log5
log5是否能变成lg
2(lg根号下2)^2+(lg根号下2)(lg5)+|lg根号下2-(log2底5)(log5底2)|=?
lg
计算:lg(1/2)-lg(5/8)+lg(12.5)+log2为底3*log3为底8=
27^2/3-2^log2^3xlog2^1/8+lg^4+2lg^5等于
log9 ((4^更号27)/3)+lg 20+log100 25+5^(log5 2)对数计算
(log9 4^更号27)/3+lg 20+log100 25+5^(log5 2)对数计算题
为什么lg(log2 10)与lg(lg2)互为相反数
1/2lg32/49-4/3lg根号8+lg根号245+2的1+log2 3
(lgx)/(lg1/2)=lg(x)/-(lg2)=-(lg(x)/lg(2))=-log2(x)
(1)1/2lg3+3lg√2-lg√6/5=?(2)log5(底数)10(真数)-log5(底数)2/√5(真数)=?
不等式lg(x-3)+lg(x-2)
