Question

对数的加减乘除运算规则

Answer 1

1、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)

Answer 2

我就不写底数了。
loga+logb=log(ab)
loga-logb=log(a/b)

（lg5）^2+lg2·lg50=?
(log2 125+log4 25+log8 5)·(log125 8+log25 4+log5 2)=?
解答：
（lg5）^2+lg2·lg50=(lg5)^2+lg2*(lg5+1)=lg5*(lg5+lg2)+lg2=lg5*lg10+lg2=lg5+lg2=lg10=1(log2 125+log4 25+log8 5)·(log125 8+log25 4+log5 2)=((lg125/lg2)+(lg25/lg4)+(lg5/lg8))((lg8/lg125)+(lg4/lg25)+lg2/...
