log9(16) ×log2(27)=6步骤

log9(16) ×log2(27)=6步骤 log5[log2(log9/log3)]=? log2 根号2+log9 27+4^log4 13=? log9(log2(8)) = x ,求x log9 3+log9 27=怎么求~ （log2 3+log4 27）*（log3 4+log9 8）=log2的2是下标,后同 log9^27= log2^根号下2+log9^27+4^(log4^13) log4(3)*log9(2)+log2(4倍根号下64) log9(32)*log64(2log4(3)*log9(2)+log2(4倍根号下64) log9(32)*log64(27)+log9(2)*log4(根27) log2(log9 3)的值 设log2 3=a,log2 5=b,则log9 15=? log9 16×log32 81= 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! log2 (log2 16)=? 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 (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 log2底24+log7底343-log2底3+(log9底8乘log16底27)如题
