(lg5)^2+(lg2)lg50
=(lg5)^2+(lg2)lg5*10
=(lg5)^2+(1-lg5)(lg5+1)
=(lg5)^2+[1-(lg5)^2]
=1

化简 (lg5)^2+(lg2)lg50 lg5²+lg2*lg50化简 (lg5)^2 + (lg2)*(lg50)= (lg5)^2+lg2*lg50 求值求解(lg5)^2+lg50*lg2 1 (lg5)^2+lg50*lg2 lg50+lg2*lg5+(lg2)^2= lg50+lg2*lg5+lg²2=? 计算（lg5)^2+lg2·lg50 (lg5)2+lg2×lg50要过程 1.（lg5）2次方+lg2*lg50 ：(lg5)的2方+lg2乘lg50
