高中数学速答一题log(ad)b=c/d意味着log(a)b=c
高中数学速答一题log(ad)b=c/d意味着log(a)b=c
log a b*log b c=log b b*log a c成立吗
利用换底公式证明:log(a)b.log(b)c.log(c)a=1
log(a)(b)=log(c)(b) /log(c)(a) 怎么证
a^[log(a)b×log(b)c×log(c)N]
对数函数题 log a - log b = 3 log (c/2) 求 a = ______________
2log(b)x=log(a)x+log(c)x
已知a、b、c为直角三角形三边,c为斜边.log(a+b)+log(c-b)=2log(b+c)alog(c-b)a
求证明 a^(log(c)(b))=b(log(c)(a))
如果a平方+b平方=c平方且c± b≠1.求证:log(c+b)a+log(c-b)a=2log(c+b)a×log(c
2^a=log(1/2)a,(1/2)^b=log(1/2)b,(1/2)^c=log(2)c,比较a,b,c的大小
[log (底数为a) x]=[1\2log (底数为a) b ] - [ log (底数为a)c]求X
