a∧log(a)m为什么等于m?

a∧log(a)m为什么等于m? Nlog(a)(M)是否等于log^N(a)(M) log(a)(mn)=log(a)(m)+log(a)(n)为什么呀? log(a)M+log(a)N=? 为什么log(a^n)(M)=1/n×log(a)(M) 证明a(log(m)n)=n(log(m)a) log a (m^n)=(log a m)^n? 推导log(a)(M/N) 求证 log(a) (M·N)=log(a) M+log(a) N log(下标a)(M*N)是什么意思?= log(下标a)M+log(下标a)N 已知ab=M（a>0,b>0,M不等于1）,且log(M)(b)=x,ze log(M)(a)等于_____ log(a)M＝m,log(a)N＝n,怎么得出 log(a)(M×N)＝m+n log[a]M^b=log[b根号a]M=b*log[a]M的具体计算过程 对数换底公式证明?log a^m b^n= n/m log a b 为什么我证明出来是=m/nlog a b 证明：log(a)(M^n)=nlog(a)(M) log(a^n)(M)=1/nlog(a)(M).. log(a)(M-N)怎样算 log(a^n)M= 1/n log(a)(M) log(a^n)M= n log(a)(M) 哪个对啊求神回复
