1/(log1/4 1/9) +1/(log1/5 1/3)等于
1/(log1/4 1/9) +1/(log1/5 1/3)等于
log1/2(9^(x-1)-5)=log1/2(3(x-1)-2)-2
log1/4(x+3)-log4(x-1)=log1/4(x+9)?
解不等式log1/3(2x-1)
对数函数比大小.log1/2 3,log1/5 3下列函数哪些大于0,哪些小于0?为什么?①log7 1/2 ②log1
3/8*log3/8+1/4*log1/4 怎么算
log1/3(1/5),log1/5(1/3),log5(1/3),log3(1/5)比较大小
log1/2 x≥1 x等于多少
log4(x+3)+log1/4(x-3)=log1/4(x-1)+log4(2x+1),说明:
解下列不等式log1/2(3x-1)>log1/2(x+1)-1
比较log1/2 1/3 与 log1/3 1/2的大小
log1/2X≥1/2=log1/2√1/5
