(lg5)2+lg2×lg50要过程(lg5)2指LG5的平方

（lg5)^2+lg2*lg50 (lg5)2+lg2×lg50要过程(lg5)2指LG5的平方 lg2*lg50+lg5*lg20-2lg5*lg2 化简 (lg5)^2+(lg2)lg50 (lg5)^2+lg2*lg50 求值 (lg5)^2+lg2×lg50=? (lg5)^2 + (lg2)*(lg50)= (lg5)^2+lg2*lg50= lg50+lg2*lg5+(lg2)^2= 问道对数题 lg2*lg50+lg20*lg5-2lg5*lg2 计算（lg5)^2+lg2·lg50 1.（lg5）2次方+lg2*lg50 计算:(lg5)2+lg2*lg50=? lg50+lg2*lg5+lg²2=? (lg5)^2+lg2·lg50=?求救... （lg5)²+lg2×lg50 那个...(lg5)^2+(lg2)lg50怎么算在下刚学对数,虽然看了个答案但还是不明白（lg2)lg50怎样变成(1-lg5)(lg5+1)原解题过程如下：(lg5)^2+(lg2)lg50=(lg5)^2+(lg2)lg5*10=(lg5)^2+(1-lg5)(lg5+1)=(lg5)^2+[1-(lg5)^2]=1 ------------- 计算 lg5^2+lg2*lg5+lg2要过程
