对数函数的运算,对数函数的运算怎么做的 ?
摘要1对数函数的运算、a^(log(a)(b))=b 2、log(a)(a^b)=b 3、log(a)(MN)=log(a)(M)+log(a)(N); 4、log(a)(M÷N)=log(a)(M
1对数函数的运算、a^(log(a)(b))=b
2、log(a)(a^b)=b
3、log(a)(MN)=log(a)(M)+log(a)(N);
4、log(a)(M÷N)=log(a)(M)-log(a)(N);
5、log(a)(M^n)=nlog(a)(M)
6、log(a^n)M=1/nlog(a)(M)
对数运算是对数函数的基础,所以一定要学好,熟悉运用公式是关键,多做点例题吧,希望你学有所成
