要过程
计算 lg5^2+lg2*lg5+lg2要过程
lg5^2=lg5+lg5
lg5+lg2=1
lg5^2+lg2*lg5+lg2
=1+lg5+lg2*lg5
=1+lg5(1+lg2)
=1+lg5(lg20)
计算：(lg5)^2 +lg2 *lg5
计算(lg5)^2+lg4*lg5+(lg2)^2
计算(lg2)^2+(lg5)^2+2lg2*lg5
2lg5+(lg2)^3*(2lg5+lg2)计算~
计算 lg5^2+lg2*lg5+lg2要过程
计算(lg2)²+(lg5)²+2lg2*lg5
lg5+lg5*lg2+lg2*lg2
如何计算2lg5+2lg2+lg5*(2lg2+lg5)+(lg2)^2
lg2(1+lg5)+(lg5)^2
(lg5)^2+lg5.lg2=
2lg2（lg2+lg5)+2lg5得数
(lg2)^2+lg2*lg5+(lg5)^2=
lg2*lg50+lg5*lg20-2lg5*lg2
(lg5)平方+2*lg5*lg2+(lg2)平方
(lg2)^2+lg5*lg20
(lg2)^2+lg20*lg5
（lg5)^2+lg2*lg50
3+lg5+(lg2)^2
