(1/2)^(log2^ 3)怎么算,公式最好写一下,求质量,

[log2(3)]^2怎么算? 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？ =[1/(log2 3)+lg2 3]²-[1/(log2 3)]²-(log2 3)²=2*(1/log2 3)*log2 3,怎么转的啊 f(log2 1/3)=-(2^(-log2 1/3)-1)=-2 怎么算就是 -(2^(-log2 1/3)-1)=-2 是怎么来的 2^[log2(1/3)]=1/3怎么算, （1/2）的（log2[3]）怎么算啊 (1/2)^(log2^ 3)怎么算 等于多少 过程 2^log2^8/3怎么算 1/2^(log2(12))怎么算? |[log2(x)]^2-3log2(x)+1| (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 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8) log2*1/25怎么算 log2根号2怎么算? 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 log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1 化简log2 1/2+log2 2/3+log2 3/4+.+log2 31/32 计算：（1）log2 (4^3*8^5);(2)log2 3+log2 6-log2 9
