求值log2^3+log2^√3/log2^9-log2^√3

求值log2^3+log2^√3/log2^9-log2^√3 求值【log2^3+log2^√3/log2^9-log2^√3】-2013^0 9^log2(3) 求值 求值:log2(32)+log2(6)-log2(3/4) log2 6-log2 3 log2^6-log2^3 log2(4)/log2(3) 数学对数函数 (6 16:21:23)log½3＋log2 3+log4 1／9+log√2 √3,求值 求值(log43+log83)(log32+log92) 注：log后面那为数是底数=5/6*log3/log2*3/2*log2/log3=5/4 怎么来的 求值：log2 (5/56)^(1/2)+log2 (14)-(1/2)log2 (35)=log2中2为底数=1/2[-2log2 (7)-3]+log2 (2)+log2 (7) 中的1/2[-2log2 (7)-3]是怎么得到的？ log2 3/log2 5等于log2 3-log2 5么? 计算：log2(log2 32-log2 3/4+log2 6) log的计算 ：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2[log2(32)-log2(3÷4）+log2log的计算 ：log2（20）-log4（25)= log3(2)×log2（5）×log5（3）=?log2【log2(32)-log2(3÷4）+log2（6）】=?lgx+lg（x+15）=2 ..X 已知log2=a及log 3=b,以a及b表示log2/27. 求值：[log6(3)]^2+log6(18)/log2(6)[log6(3)]^2+log6(18)/log2(6) (log2 5+log4 125)log3 2/ log根号3 5 log2/27及 log 3=a log5=b log2(3)×log2(4)=log2(7)?log2(3)×log2(4)=log2(7)吗?log2(1/49)+log2(1/16)+log2(1/27)等于多少呢?帮个忙!
