方程log2[log3(log4(x))]=0的解集为?
方程log2[log3(log4(x))]=0的解集为?
方程log2[log3(log4(x))]=0的解集为?
log2[log3(log4(x))]=0
log3(log4(x))=1
log4(x)=3
x=4^3=64
根据对数式化为指数式,
得:log2[log3(log4(x))]=0
[log3(log4(x))]=2^0=1
log4(x)=3^1=3
x=4^3=64
方程log2[log3(log4(x))]=0的解集为?
解方程:log4{2log3[1+log2(1+3log2 x)]}=1/2
解方程log3(log4(x))=0
若log2[log3(log4)]=0,求x
log3 (log4 x)=0 对数方程,

(log2 3+log4 27)(log3 4+log27 16)
log2^(log3^x)=log3^(log4^y)=0则x+y=
对数方程log2(x-1)=log4 x,如何化成log2(x-1)²?
已知log2[log3(log4x)]=log3[log4(log2y)]=0,求x+y
已知log2(log3(log4x))=log3(log4(log2y))=0,求x+y的值
已知:log2[log3(log4x)]=log3[log4(log2y)]=0 求x+y的值
log2[log3(log4x)]=log3[log4(log2y)]=0求x+y的值,
指数方程与对数方程1)若logx2√2=3/4,则x=2)对数方程log3(X-1)+log3(X+1)=1的解集是3)对数方程log4(3x-2)=log2(x-2)的解是4)指数方程5^x-5^-x+1-4=0
若x=24,则1/log2 (x)+1/log3 (x)+1/log4 (x)等于
对数方程log2(x-1)=log4 x,如何化成(x-1)²=x
若log2【log3(log4 x)]=0,求x的值
若log2^3×log3^4×log4^x=log9^3 ,求x
