高一对数运算:计算lg^3(2)+lg^3(5)+3lg(2)lg
求值 lg 2lg 50 + lg 5lg 20 - lg 100lg 5lg 2
求值(lg 2)^2 lg 2lg 5 lg 50
2lg²2+lg²5+3lg2lg5-lg2
计算:lg³2+lg³5+3lg2lg5
2(lg√2)^2+lg√2.lg√5+√[(lg√2)^2-lg2+1]
计算:lg(1/2)-lg(5/8)+lg(12.5)+log2为底3*log3为底8=
27^2/3-2^log2^3xlog2^1/8+lg^4+2lg^5等于
2lg(5/3)-lg(7/4)+2lg3+(1/2)lg49
(lg√27+lg8-3lg√10)/lg1.2
这一步是怎么化简的lg(x - 1) > (3/2)*lg(3) = lg(3√3)
