我有做过么?原题给我看看
y=-log(0.2)(x-1)
=log5 (x-1)

log5(x^2+2x-2)=0,2log5(x+2)-log5y+1/2=0求y
已知log2[log1/2(log2x)]=log3[log1/3(log3y)]=log5[log1/5(log5z)
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5
1.求下列函数的定义域:(1)y=log5 (1-x);(2)y=1/(log2 x);(3)y=log7 1/1-3x
数学指数函数问题麻烦解释下y=log5(x+1) y=1/(log2(底数)X) y=log7(底数)1/(1-3x)
a=log5(5x)=1+log5(x)
y=log5(2x²-x+1)值域
对数.很简单log5x=0log5x=1log5(log3x)=1
y=根号[log3^(log0.5^x)-1]定义域(过程)
求下列函数的定义域:⑴y=[1-log3(x2+2x)]的-1次方⑵y=log5x+3(a的x次方-1)⑶y=log3[
