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(4)/log2(3) 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! 计算：log2(log2 32-log2 3/4+log2 6) log2 6-log2 3 log2^6-log2^3 log2 (log2 16)=? [log2 1]+[log2 2]+[log2 3]+[log2 4]+[log2 5]+...+[log2 1024]=?[x]表示不超过x的最大整数2为底 答案是8204 (log2 9)/(log2 8) = 2/3(log2 3) log2^(4^7*2^5)+log2^6-log2^3 求值:log2(32)+log2(6)-log2(3/4) log2 5/4+log2 5=多少, log2(log2 log2^5+3= 2log2^3= log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1 计算：（1）log2 (4^3*8^5);(2)log2 3+log2 6-log2 9 化简log2 1/2+log2 2/3+log2 3/4+.+log2 31/32 log2 3/log2 5等于log2 3-log2 5么?
