化简求值:lg²2+lg4lg50+lg²50=?
化简求值:lg²2+lg4lg50+lg²50=?
求值 lg 2lg 50 + lg 5lg 20 - lg 100lg 5lg 2
求值(lg 2)^2 lg 2lg 5 lg 50
lg²2+lg2×lg5+lg²5=?
(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
(lg根号8+lg27-lg根号1000)÷lg1.8 化简求值
这一步是怎么化简的lg(x - 1) > (3/2)*lg(3) = lg(3√3)
lg50+lg2*lg5+lg²2=?
(lg²2-lg2*lg5+lg²)+3lg2*lg5
lg²2+lg2×lg5+lg²5
lg²2等于多少.
