(log2 9)/(log2 8) = 2/3(log2 3)
2log2^3=
log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1
[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
求解log2(3x)=log2(2x+1)
(log2 6)×(log3 6)-(log2 3+log3 2)=
(log2 6)×(log3 6)-(log2 3+log3 2)=
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?
log2(3)*log3(2)=?
(log3^2)(log2^3)=
解方程log2(x+14)-log2(x+6)=3-log2(x+2)
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!
=[1/(log2 3)+lg2 3]²-[1/(log2 3)]²-(log2 3)²=2*(1/log2 3)*log2 3,怎么转的啊
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
log2 3乘以log2 3等于2log2
log2^(4^7*2^5)+log2^6-log2^3
|[log2(x)]^2-3log2(x)+1|
2log2 10—log2 25=?
