(log5)^2 + (log50)(log2)
(log5)^2 + (log(5*10))(log2)
=(log5)^2 + (log5 + log10)(log2)
=(log5)^2 + (log5 + 1)(log2)
=(log5)^2 + (log5)(log2) + log2
=(log5)(log5 + log2) + (log2)
=(log5)(log10) + (log2)
=(log5)(1) + (log2)
=(log5) + (log2)
=(log10)
=1

高一数学(log5)^2+log2·log50 求下列各式的值 1）log2 6+log2 3 2)lg5+lg2 3)log5 3+log5 三分之一 4）log3 log的计算：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2[log log2 25*log3 4*log5 9 的值为（）A 6 B8 C15 D 30 比较log2＾（1/3）,log1/3＾2,log5＾2的大小求x的值 log4^x=-2/3 log2^(log5^x)=0 log2(3)*log3(5)*log5(8)（具体步骤）高中对数log2(9)*log3(根号5）*log5（2）计算：（lg2)2+3lg5+lg5(1+lg2)+lg8+log2（5）log5（4) 设m=log5（8）；n=log2（5）,则m与n的大小关系是.求详解, 若3/log2 19+2/log3 19+1/log5 19=log19 m,求m的值（1）求10^log10 3-10^log5 1+π^logπ 2的值
