log2 20---log2 5+log3 4 * log4 3 等于什么
log2 20---log2 5+log3 4 * log4 3 等于什么
log2 20---log2 5+log3 4 * log4 3 等于什么
log2 20-log2 5+log3 4 * log4 3 =log2 4+log 2 5-(log2 5)+1
=2+log2 5-(log2 5)+1=3
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/log2 5等于log2 3-log2 5么?
log2 5/4+log2 5
(log2 5+log4 125)log3 2/ log根号3 5
log根号2^(x-5)log2^(x-1)
log根号2^(x-5)-log2^(x-1)
log2 20---log2 5+log3 4 * log4 3 等于什么
log2(20)-log2(5)+2log3(2)×log4(3)
log2(log2
解方程:log2(9^x - 5)=log2(3^x - 2)+2解方程log2(9^x - 5)=log2(3^x - 2)+2希望有详细过程.注:log2中的2为log的下标
log (log2)^2 - (log4)(log20) + (log20)^2
log2(3)*log3(4)*log4(5)*.log(k+1)(k+2)=log2(k+2) 怎么证
log2 5 x log2 5等于log2 25还是什么?
log2^(4^7*2^5)+log2^6-log2^3
log2 5/4+log2 5=多少,
3^(log2 (5))-5^(log2(3))
log2 50-2log2 5 等于多少?
2^log2(20)=?
