log[a]M^b=log[b根号a]M=b*log[a]M的具体计算过程
证明:log(A)M=log(b)M/log(b)A (b>0且b≠1).
证明log(a^m)b^n=(n/m)log(a)b
log a^m(b^n)=(n/m)*log a(b)
求对数函数公式的推导log(a)(M^n)=nlog(a)(M) 和log(a)(N)=log(b)(N) / log(b)(a) 的推导
换底公式推导过程1.log(a)(b)=1/log(b)(a) 2.log(a^n)(b^m)=m/n*[log(a)(b)] 3.log(a)(M^n)=nlog(a)(M)
log(a)M+log(a)N=?
证明:log(a)M*log(b)N=log(a)N*log(b)M.对调真数的位置,对数的积不变.
已知log(14)7=a log(14)5=b 用ab表示log(35)70=log(3)4*log(4)8*log(8)m=log(4)2 求m
log 3 m=a,log 5 m=b,1/a + 1/b =2,m=?
log a b^n/log a a^m 什么运算法则得log a b^n/m
对数的几个推论:①log(a^m)b^m=___log(a)b 求log(a)b前的系数②log(a)b*log(b)c*log(c)d=?
证明a(log(m)n)=n(log(m)a)
log a (m^n)=(log a m)^n?
log(a^N)(b^M)=M/Nlog(a)(b)怎么推导?
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
已知ab=M(a>0,b>0,M不等于1),且log(M)(b)=x,ze log(M)(a)等于_____
对数函数公式规律形如:log(a)【b】(有方根用:‘数字 谢谢)如:log(a)【M】+log(a)【N】=log(a)【MN】log(a)【M】-log(a)【N】=log(a)【M/N】log(a)【M】-log(a)【N】
