(log(3)2+lg(9)2)(log(4)3+log(8)3)

(log(3)2+lg(9)2)(log(4)3+log(8)3) 用换底公式简化[log(4)3+log(8)3][log(3)2+log(9)2] (log(4)3+log(8)3)(log(3)2+log(9)2) 怎么个思路 (log(4)3+log(8)3)(log(3)2+log(9)8) 怎么个思路 对数计算1.{log(4)（3）+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log( log(2)9×log(3)4 log(2)9log(3)4等于 (Log(4)3+log(8)3)(log(3)2+log(9)2) 顺便问下lg3乘lg4=lg（3+4）? log(3)4*log(4)8*log(8)M =log(2)16 M是多少 log(2)(25)*log(3)(根号2)*log(5)(9) （LOG(3,4)+LOG(3,8)）（LOG(2,3)+LOG(2,9)）等于几 看的懂吧 有关对数的计算题(log(4)3+log(8)3)(log(3)2+log(9)2)=?
