[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^(4^7*2^5)+log2^6-log2^3
lg(1/4)-lg2(5) 2log5(10)+log5(0.25) 2log2(25)-3log2(64) log2(log2(16) )
根号下{[log2 (5)]^2-4log2(5)+4}+log2(1/5)
计算 根号下[(log2 5)^2-4log2 5+4]+log2 1/5
化简log2 1/2+log2 2/3+log2 3/4+.+log2 31/32

4的1/2(log2底9-log2底5)的次方等于多少?
(log2) ^2 - log5 *log20课本上 等于 (log2)^2 +(1+log2)(1-log2) = 1;(log2)^2 +(1+log2)(1-log2) 是怎么来的?
log2 5/4+log2 5
已知函数f(x)=log2^ ( x/4 ) ×log2^ (2x) (1)解不等式f(x)>0;(2)当x∈【1,4】时,求f(x)的值域f(x)=log2(2x)×log2(x/4)=[(log2 2)+(log2 x)] ×[(log2 x) -(log2 4)]=[1+(log2 x)] ×[(log2 x) -2]=(log2 x)² - (log2 x) -2
log2(2^x-1)log2(2^(x+2)-4=3log2(2^x-1)log2(2^(x+2)-4)=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!
(log3^4+log5^2)(log2^9+log2^根号3)
解不等式:|log2(x-1)|+log2(5-x)
解2log2^(x-5)=log2^(x-1)+1
