(lg5)^2+lg2·lg50=?
求救...

lg²5+lg2•lg50
=lg²5+lg2•lg(5•10)
=lg²5+lg2•(lg5+lg10)
=lg²5+lg2•lg5+lg2
=lg5•(lg5+lg2)+lg2
=lg5•[lg(5•2)]+lg2
=lg5•lg10+lg2
=lg5+lg2
=lg(5•2)
=1

(lg5)^2+lg2·lg50=? (lg5)^2 + (lg2)*(lg50)= lg50+lg2*lg5+(lg2)^2= 计算（lg5)^2+lg2·lg50 lg50+lg2*lg5+lg²2=? 计算:(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(lg2)²+2lg2·lg5+(lg5)²+lg50－lg5求答案, lg^2 2+2lg5+lg2·lg50
