(log8^27)/(log4^9)的值

(log8^27)/(log4^9)的值 化简：（log2(3)+log4(9)+log8(27)+…+log2n(3^n))*log2(8的n次方根) (log2 3+log4 9+log8 27+...+log2^n 3^n）log9 32的N次方根 (log2 3+log4 9+log8 27+...+log2^n 3^n）log9 32的N次方根 已知½log8（a）+log4（b）=5/2,log8(b)+log4(a^2)=7 求ab的值 log4(12)与log8(27)的差和log4(27)与log2(6)的差的比值为 化简log3(4)*log4(5)*log5(8)*log8(9)的结果是? 求(log3^2 + log9^2)×（log4^3 + log8^3)的值.请给出过程,谢谢! log4(3)-log4(12)-log8(4) =log4(3/12)- log8( 8^(2/3) ) log8( 8^(2/3) )怎么得出来的? 求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16) ：若log3(4)*log4(8)*log8(m)=log4(16),则m等于( )A 1/2 B 9 C 18 D 27答案是B但为什么? log3^36-log3^4+log2(log2^16)+8^2/3+(27/8)^-1/3+log8^27/log4^9怎么算啊,不好意思哦,我已经没分啦.麻烦一下写一写log2(log2^16) (27/8)^-1/3 log8^27/log4^9 计算（log2 3+log4 9+log8 27+……+log2^n 3^n）log9 n次根号3计算（log2 3+log4 9+log8 27+……+log2^n 3^n）log9 n次根号32 1.log18/25(2/5)2.log4 27×log8 25×log9 5( 8和25是上下并列写的, log27^4*log8^9+2log4^9-4 要崩溃了- -表示不认真听课的下场啊.. log27^4*log8^9+2log4^9-4 要崩溃了- -表示不认真听课的下场啊. log4 8-log8 4=? log8^9/log2^3的值是
