(lg2)²+2lg5+lg2·lg50
=lg2·(lg2+lg50)+2lg5
=lg2·lg(2·50)+2lg5
=lg2·lg100+2lg5
=2lg2+2lg5
=2·(lg2+lg5)
=2·lg(2·5)
=2lg10
=2

lg50+lg2*lg5+lg²2=? lg^2 2+2lg5+lg2·lg50 计算：｜lg2-lg^2(5)｜+lg2·lg50+√(lg5-1)^2 lg²2+lg50+lg2*lg5怎么解答（步奏计算（lg5)^2+lg2·lg50 (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 lg50+lg2*lg5+(lg2)^2=
