(lg²2-lg2*lg5+lg²)+3lg2*lg5
2 lg2 + lg5 / lg√10
2lg2+lg5/lg√10=?
(lg^2)2+lg2*lg5+lg5
lg²2+lg2×lg5+lg5
lg^2 5+lg2*lg5+lg2=?
(lg^2)2+lg2*lg5+lg5=lg2(lg2+lg5)=lg2+lg5=1 为什么能把lg2提出来?lg2*lg10为什么等于lg2
lg^2 5+lg5*lg2+lg2 怎么算lg^2 5+lg5*lg2+lg2 怎么算
2(lg√2)^2+lg√2*lg5+√(lg)√2^2-lg2+1
lg2(1+lg5)+(lg5)^2
计算:|lg2-lg^2(5)|+lg2·lg50+√(lg5-1)^2
lg5×lg(5×2)+lg2怎莫算具体
lg50+lg2*lg5+lg²2=?
2(log√2)+lg√2*lg5+√(lg√2)-lg2+1
对数lg2*lg5=?2lg(5)+2/3 lg8+lg5*lg20+lg2 =lg5^2+lg8^(2/3)+lg5*(lg4+lg5)+lg2 =lg100+lg5+2lg2*lg5+lg2 =2+(lg5+lg2) =2+1 =3 第二个等号lg5*(lg4+lg5)为什么=lg5+2lg2*lg5
(lg√2)^2+1/2lg2*lg5+√(lg√2)^-lg2+1 化简求值
(lg√2)^2+1/2lg2*lg5+√(lg√2)^-lg2+1 化简求值
(lg8+lg1000)lg5+3(lg2)^2+lg^-1+lg0.006
