9^log2(3) 求值

9^log2(3) 求值 求值log2^3+log2^√3/log2^9-log2^√3 求值【log2^3+log2^√3/log2^9-log2^√3】-2013^0 求值:log2(32)+log2(6)-log2(3/4) 求值:log8(底数)9/log2(底数)3 (过程） 求值!log2(cos湃/9)+log2(cos2湃/9)+log2(cos4湃/9)答案是-3,『湃就是3.1415926...』 ( log8^9 )/( log2^3 )求值其中2和8是底数 3和9是真数 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？ 求值：【log2（3）+log4（9）+log8（27）+log16（81）+log32（243）】—5log2（3/2) 求值：[log6(3)]^2+log6(18)/log2(6)[log6(3)]^2+log6(18)/log2(6) (log2 9)/(log2 8) = 2/3(log2 3) log8(9)*log2(3) 计算：（1）log2 (4^3*8^5);(2)log2 3+log2 6-log2 9 求值:log2(cosπ/9)+log2(cos(2π)/9)+log2(cos(4π)/9)log后的2为下标, 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
