解
2(lg5)²+2lg2lg50
=2(lg5)²+2lg2(lg5+1)
=2(lg5)²+2lg2lg5+2lg2
=2lg5(lg5+lg2)+2lg2
=2lg5lg10+2lg2
=2lg5+2lg2
=2(lg5×2)
=2

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