4lg2+3lg5-l 1 g- 5
计算:(lg2)2+3lg5+lg5(1+lg2)+lg8+log2(5)log5(4)
1.lg²5+lg2×lg5+lg2 2.(lg2)³ +(lg 5)³ +3lg 2×l
lg2(lg5-lg2)-lg5(lg5+3lg2)等于
lg2(1+lg5)+(lg5)^2
(lg2)^3+(lg5)^3+3*lg2*lg5
(lg2)³+(lg5)³+3lg2×lg5
0.01^(-1/2)-log0.5底8+3^(log3底2)+(lg2)^2+lg2*lg5+lg5=?
2lg2+3lg5-lg1除以5
3+lg5+(lg2)^2
1/2(lg2)^2+1/2lg2*lg5+√1/4(lg2)^2-lg2+1=?
lg5(1-lg5)+2lg5根号2+lg2(1-lg5)
[(lg2)^3+(lg5)^3-1]/[(lg2)^2+(lg5)^2-1]=多少 怎么算
