求值:2log(角标3)2-log(角标3)32/9+log(角标3)8-5^log(角标5)3等于?

log(2)(25)*log(3)(根号2)*log(5)(9) log(2)9log(3)4等于 log（2）25×log（3）4×log （5）9等于多少? log(3)2-log(3)32/9+log(3)16 - 5的2log（5)3次方 -5log⑨4+log③32/9-5^log⑤3-（1/64)^-2/3 log(2)1/25乘以log(3)1/8乘以log(5)1/9 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 （LOG(3,4)+LOG(3,8)）（LOG(2,3)+LOG(2,9)）等于几 看的懂吧 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
