对数相乘等于真数相加（对数相乘）
导读 log(a)(b)=1/log(b)(a)log(a)(N)=log(b)(N)÷log(b)(a)a^(log(a)(b))=b 2、log(a)(a^b)=b 3、log(a)(MN)=log(a)(M) log(a)(N); ...
log(a)(b)=1/log(b)(a)log(a)(N)=log(b)(N)÷log(b)(a)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)这些都是对数的公式对数不是高中最重要的那个类型来的。
