4^log(3)(4)+4^-log(3)(4)怎么算, (log(4)3+log(8)3)(log(3)2+log(9)8) 怎么个思路 (log(4)3+log(8)3)(log(3)2+log(9)2) 怎么个思路 log(2)9×log(3)4 log(2)9log(3)4等于 log(27)16/log(3)4= 2 log(3x)= log 4 +log(6-x)怎么求...急 化简log(2)3 * log(3)4 * log(4)7 *log(7)16 log(3)4*log(4)8*log(8)M =log(2)16 M是多少 用换底公式简化[log(4)3+log(8)3][log(3)2+log(9)2] 对数计算1.{log(4)（3）+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log( 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x
