lg5*lg5 是(lg5)^2还是lg(5^2)还是lg10
(lg根号27+lg5-lg10根号2)/lg1.5
是表示lg2乘lg5还是表示lg(2lg5)?
(lg2)2[2lg5+1]+(lg5)2[2lg2+lg10]
lg2×lg5=?lg2×lg5=lg?求问号..是lg(2+5)吗?
(lg²2-lg2*lg5+lg²)+3lg2*lg5
lg^2 5+lg2*lg5+lg2=?
lg5×lg(5×2)+lg2怎莫算具体
lg5(1-lg5)+2lg5根号2+lg2(1-lg5)
lg2^2+lg2*lg5+lg5=lg2(lg2+lg5)+lg5
计算:(lg5)^2 +lg2 *lg5
(lg5)^2+lg5.lg2=
lg2(1+lg5)+(lg5)^2
