log(9)(16)*log(8)(81)能用换底公式解吗我将上述公式化为【log(10)(16)/log(10)(9)】*【log(10)(81)/log(10)(8)】=(16/9)*(81/8)=18,结果错了,求正解,还有我为什么错了?

log(16) 9*log(27) 32=?
(log(8)9)/log(2)3
log(8)9-log(27)32的值,
求log(8)9-log(27)32的值,
化简(log[4]3+log[8]3)×(log[3]2+log[9]2)如题
(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(2)(3)} X {log(3)(4)+log(9)(2)}3.(lg2)^+1g2X 1g5 +1g50
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3)

化简2log`5(10)+log`3(0.25)+log`1/5(125)=(2) log`2(根号2)+log`9(27)+(1/4)^log`4(1/16) 注意 `为下角标
求值 log(2)9×log(3)2
计算:log(a)16×log(4) a
求值,(log(6)4+log(6)9)^2
如何计算啊.(log底数4真数3+log底数8真数3)乘(log底数3真数2+log底数9真数2)=?
问道数学题(高一)(对数)化简:(log 3 + log 3)(log 2 + log 2) 4 8 3 9有些过程,拜托了.
高一函数【运算对数】运算:(log【2】3-log【4】27)×(log【3】4+log【9】8)【 】内的是底数.
求值 log【9(下标)】3+log【 9(下标)】27 log【2】(1/2)- log【1/2】2
(Log(4)3+log(8)3)(log(3)2+log(9)2) 顺便问下lg3乘lg4=lg(3+4)?
