1/(1+log3 2)+1/(1+log2 3)=lg3/(lg2+lg3)+lg2/(lg2+lg3)=1解释一下这条式子是怎么转换的

log3 2+log3 1/2 +lg20 +lg5等于多少 log3(x^2-3)=1+log3(x-5/3) log3 5-log3 15+1/2log9 27 的值 log3（2）+log3（x)=1,则X=? 计算log3[(9^2 * 27^(1/3))/3^(log3 234)] log3¹²怎么化成2log3²+1 log3(2)+log3(x)=1,则x=? 已知log3(2x-1) 关于对数函数log3 (x^2+2)=log3 x+1以log3为底 log3 1等于几 log3(lgx)=1 log3^18-2log3^2的值有选项的 A.1 B.2 C.0 D.log3^2 log3（2）,log3(2^x-1),log3(2^x+11)成等差数列,则x的值为 3^(1+log3 6) -2^(4+log2 3)+10^3lg3+(9/1)^log3^4题有个错误，+(9/1)^log3^4改为+(9/1)^log3^4-1 计算(log3 2)(log2 6-1) log2 1-lg3×log3 2-lg5 解不等式：log3(2x-1) log2 1-lg3×log3 2-lg5
