log2 50-2log2 5 等于多少?
log2(50)-2log2(5) 已知log6 2=0.3869,求log6 3
log2^(4^7*2^5)+log2^6-log2^3
已知log2
log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
计算:(1)log2 (4^3*8^5);(2)log2 3+log2 6-log2 9
log2 3/log2 5等于log2 3-log2 5么?
log2 5/4+log2 5
[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(20)-log2(5)+2log3(2)×log4(3)
log2 5/log2 3为什么等于log3 5 log2 5,log2 3的2是角标 log3 5的3是角标log2 5/log2 3为什么等于log3 5log2 log2 3的2是角标,log3 5的3是角标
4^1/2(log2^9-log2^5)的值 ,
解2log2^(x-5)=log2^(x-1)+1
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(log2
log2(4^7*2^5)
2log2 5等于多少?
