log(a)*log(b)=啥啊,忘记公式了啊 别告诉我等于log(b)*log(a)

log(a)*log(b)=啥啊,忘记公式了啊 别告诉我等于log(b)*log(a) log(a)(b)=log(c)(b) /log(c)(a) 怎么证log(a)(b)=log(c)(b) /log(c)(a)怎么证 公式：log(a)(b)*log(b)(a)=? 求证 log(a)^(b)=1/log(b)^(a)求证 log(a)^(b)=1/log(b)^(a) matlab中合并对数?如何实现log(a)-log(b)=log(a/b) 证明log^a+log^b=log^(a+b)要过程 log(a)b=log(c)b/log(c)a 是怎么推算来的 2log(b)x=log(a)x+log(c)x求证,c^2=(ac)^[log(a)b] 对数函数题 log a - log b = 3 log (c/2) 求 a = ______________ log(2)5=a,log(2)7=b用ab表示log(35)28 log a b*log b c=log b b*log a c成立吗中间的字母是写在下面的 相当于log的脚码 可以说log a x +log a y=log a log(8)a+log(4)b^2=5,log(8)b+log(4)a^2=7,求log(2)ab的值 log(a)M+log(a)N=? 设a>b>1,log(a)b+log(b)a=10/3,则log(a)b-log(b)a= 已知a＜b＜1,log(a)b+log(b)a=10/3,求log(a)b-log(b)a的值括号为下标, 证明：log(A)M=log(b)M/log(b)A (b>0且b≠1）. log[a]M^b=log[b根号a]M=b*log[a]M的具体计算过程
