log2^5+3=

log2^5+3= log2 3/log2 5等于log2 3-log2 5么? [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=A,LOG2^5=b,则log2^9/5值是多少 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! 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 9)/(log2 8) = 2/3(log2 3) log2^(4^7*2^5)+log2^6-log2^3 3^(log2 (5))-5^(log2(3)) log2 5/4+log2 5=多少, 5^log30*3^log2=15 log2(x^2-3)=5 计算 log2(5) ×log5(8)=3步骤 log2(3)+log3(5)+log3(2)=? 2log2^3= log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
