log4(1+√2+√3)+log4(1+√2-√3)的值等于
log4(1+√2+√3)+log4(1+√2-√3)的值等于

log4(1+√2+√3)+log4(1+√2-√3)的值等于
log4(1+√2+√3)+log4(1+√2-√3)
=log4[(1+√2+√3)(1+√2-√3)]
=log4[(1+√2)^2-(√3)^2]
=log4[3+2√2-3]
=log4(2√2)
=log4(2^3/2)
=ln(2^3/2)/ln4
=3/2*ln2/(2ln2)
=3/4

log4(1+√2+√3)+log4(1+√2-√3)的值等于 (1/4)^log4(3) log4(1+√5-√3)+log4(1+√5+√3)=? 解方程log4 x+1/log4 x=10/3 log4^8+log4^2-(1/4)^0 等于多少? 解方程 log4 (3x-1)=log4 (x-1)+log4 (3+x) log4(3x-1)-log4(3+x)=log4(x-1) 2^log4(3) log4(3x-2) 2^log4^3=? log4^(-1)等于几 log4^(-1)等于几 log4 1/8 log4 计算:(log4 3+log8 3)×log9 √2=? 比较log1/2(1/3)和log4(8)的大小. 求证log3(4)=1/log4(3) y=log4(3x+1)+1/2log4(x+1),x∈【0,1】的值域
