lg5 X lg20 - lg2 X lg50 - lg25
lg5*lg20+(lg2)^
(lg2)^2+lg5*lg20
(lg2)^2+lg20*lg5
lg2*lg2+lg20*lg5=?
lg2*lg50+lg5*lg20-2lg5*lg2
lg5·lg20+(lg2)^2
lg2*lg50-lg5*lg20-lg4
为什么lg5*lg20=lg5*(1+lg2)
lg5^2+lg4+lg5*lg20+(lg2)^@
lg5^2+lg4+lg5*lg20+(lg2)^2
lg2lg50+lg5×lg20-lg100×lg5×lg2=
(lg2)^2+lg20*lg5+(lg5)^2
（lg2)*(lg2)+lg5*lg20-1怎么计算
问道对数题 lg2*lg50+lg20*lg5-2lg5*lg2
求值lg2*lg50+lg5*lg20-lg100*lg2*lg5
(lg2)x(lg2)x(lg2)+(lg5)^3+3xlg2xlg5=?
（lg2)^2+lg5·lg20-1=?
