log(4)6能不能化简为log(2)3呢? 还有log(3)x=3分之1 x=多少 求等式log(2)3*log(3)4*log（4)5*log(5)6*log(6)7*log(7)m=log(3)9时m的值? 数学必修一化简题（log 4 3）*（log 3 2）可以化简为log 4 2那么（log 4 3）*（log 9 2）可以化简成什么? log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,求每步详...log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解, logN=log(3)6+log(4)12-log(2)9是log(2)9 是以2为底的……怎么能化成2呢？ log(2)3=a,则log(6)4=（ 4^[log(2)3+log(4)8] log(2)9log(3)4等于 log(2)9×log(3)4 log(2)2/3+log(2)6+log(4)8= 2 log(3x)= log 4 +log(6-x)怎么求...急 [log(4)3+log(8)3][log(3)2+log(9)2]-log(1/2)32∧1/4过程详细点,log(4)3是log以4为底3的对数， 问一道数学题.log(2)3*log(3)4*log(5)6*……*log(2008)2009(2)之类是在log下面,*是乘号 log以6为底[log以4为底（log以3为底81）]的值为? 化简:(log^3 2+log^9 2)(log^4 3+log^8 3) (log(4)3+log(8)3)(log(3)2+log(9)2) 怎么个思路 化简log(2)3 * log(3)4 * log(4)7 *log(7)16 (log(4)3+log(8)3)(log(3)2+log(9)8) 怎么个思路
