第1页第二章基本初等函数课题：2.2.1 对数与对数的运算设计人：宫玲玲审核人：向坤、张自强班级：姓名：问题生成评价单一、对数的概念1、对数的概念一般地，如果ax=N(a0,且 a1)，那么数 x 叫做以 _为底_的对数(logarithm),记作 x=_，其中 a 叫做对数的 _，N叫做_.以 10 为底数的对数叫做常用对数(common logarithm),并把log10N记为_.另外，在科学技术中常使用以无理数e=2.71828 为底数的对数，以 e 为底的对数称为自然对数(natural logarithm),并把logeN记为_.2、对数的性质根据对数的概念，对数logaN(a0,且 a1)具有以下性质：（1）_ 没有对数，即 N0.（2）1 的对数等于 _，即loga1=_.（3）底的对数等于 _，即logaa=_.二、对数的运算1、基本性质若 a0，且 a1，N0，则（1）logaNa=_；（2）logaab=_.第2页2、对数的运算性质如果 a0，且 a1，M0，N0，那么：（1）loga(MN)=_；（2）logaMN=_；（3）logaMn=_(nR).3、对数的换底公式对数的换底公式：logloglogcbcNNb（b0，且 b1；c0，且 c1；N0）.变形公式一：loglog1abbag变形公式二：loglognmNNmMMn文档编码:CG10I6A8B3P2 HY5J3M1H2K9 ZS9H10J4L7H1文档编码:CG10I6A8B3P2 HY5J3M1H2K9 ZS9H10J4L7H1文档编码:CG10I6A8B3P2 HY5J3M1H2K9 ZS9H10J4L7H1文档编码:CG10I6A8B3P2 HY5J3M1H2K9
