在数学计算上 ln (x2)=2lnx，但是它们的对应法则是不同的。 不能一概而论，既然写法不同，那就有所不同之处，虽然通过证明等式成立，但是等式左边x取值范围是x≠0，等式右边x取值范围 …

2ln(1 x) ln(2) = ln((1 x)2) ln(2); and applying the rule ln(x=y) = ln(x) ln(y): = ln(1 2 (1 x)2) So the original equation is equivalent to ln(x+ 2) = ln(1 2 (1 x)2); 2 < x < 1: This equation has the form …
