(1/2)的(log2[3])怎么算啊 (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? =[1/(log2 3)+lg2 3]²-[1/(log2 3)]²-(log2 3)²=2*(1/log2 3)*log2 3,怎么转的啊 计算:(1)log2 (4^3*8^5);(2)log2 3+log2 6-log2 9 2log2(12)怎么转化成log2(3)? log2(16^2*64)计算(写过程啊)这题我刚刚自己会了,我要问的是lg8/lg4怎么算[log2(8)/log2(10)]里的log2怎么来的, log4(3)+log8(3) 怎么算的我知道(1/2)log2(3)+(1/3)log2(3) 但是下一步怎么算的↓(5/6)log2(3) 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? 4^1/2(log2^9-log2^5)的值 , 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 log2(√1/48)+log2 12-1/2log2 (24)-1/3 [log2(3)]^2怎么算? log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log2(32)-log2(3÷4)+log2log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2【log2(32)-log2(3÷4)+log2(6)】=?lgx+lg(x+15)=2 ..X y=2的log2的x次方,f(-1/3)+1 这个两个怎么算的呢? log2.(x+1)的定义域是.2在下面.这个怎么算 log2(x)+1=2log2(x-a)恰有一个实数解,实数a的取值范围是_______________已知2log2(x-a)=log2[(x-a)²]接下来怎么解?(请勿复制) 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(1+根号2+根号3)+log2(1+根号2-根号3)=中有一步是怎样来的解:log2(1+根号2+根号3)+log2(1+根号2-根号3)=log2[(1+√2+√3)(1+√2-√3)]=log2[(1+√2)²-(√3)²]=log2[2√2]=log2[2^(3/2)]=3/2这里log2[2
