证明:log(a)bXlog(b)cXlog(c)a=1
证明:log(a)bXlog(b)cXlog(c)a=1
证明:log(A)M=log(b)M/log(b)A (b>0且b≠1).
利用换底公式证明:log(a)b.log(b)c.log(c)a=1
1≤a≤b≤c,证明log(a)(b)+log(b)(c)+log(c)(a)≤log(b)(a)+log(c)(b)+
求证明 a^(log(c)(b))=b(log(c)(a))
设a,b,c是直角三角形的三边长,其中c为斜边,且c≠1,求证:log(c+b)a+log(c-b)a=2log(c+b
log证明题证明:1.a^ln(n)=n^ln(a)2.log(n)=c*ln(n) (log以10为底)
证明对数运算法则(1)log(a)(MN)=log(a)(M)+log(a)(N); (2)log(a)(M/N)=
设A^2+B^2=C^2 求证 log以(C+B)为底A的对数+log(C-B)A=2log(C+B)*log(C-B)
利用换底公式利用换底公式证明:log(a)b*log(b)c*log(c)a=1括号内为底数
若log(3)(2)=a,log(6)(3)=b,则有b(1+a)=1 证明
log(2)(a)=log(3)(b)=log(5)(c)
