若log(a)b=log(b)a(a≠b,a≠1,b≠1),则ab等于若log(a)b=log(b)a(a≠b,a≠1,b≠1),则ab等于若log(a)b=log(b)a(a≠b,a≠1,b≠1),
若log(a)b=log(b)a(a≠b,a≠1,b≠1),则ab等于
若log(a)b=log(b)a(a≠b,a≠1,b≠1),则ab等于
若log(a)b=log(b)a(a≠b,a≠1,b≠1),则ab等于
ab=1.有换底公式,化为lnb/lna=lna/lnb.整理得(lnb-lna)(lnb+lna)=0.a≠b得lna≠lnb,从而lnb+lna=0.即ln(ab)=0.所以ab=1
公式:log(a)(b)*log(b)(a)=?
求证 log(a)^(b)=1/log(b)^(a)求证 log(a)^(b)=1/log(b)^(a)
log(a)(b)=log(c)(b) /log(c)(a) 怎么证log(a)(b)=log(c)(b) /log(c)(a)怎么证
证明:log(A)M=log(b)M/log(b)A (b>0且b≠1).
若a²>b>a>1,试比较log b b/a ,log b a,log a b的大小
27-1/ 若a>0,b>0,a*b>1,log(1/2)[a]=ln2,则log(a)[b]与log(1/2)[a]的关系是:()?(A)log(a)b< log(1/2)[a](B)log(a)b= log(1/2)[a](C)log(a)b>log(1/2)[a](D)log(a)b与log(1/2)[a] 无法比较大小我做到一半就做不下去了:a=(1/2)^(ln2)log
matlab中合并对数?如何实现log(a)-log(b)=log(a/b)
证明log^a+log^b=log^(a+b)要过程
log(a)b=log(c)b/log(c)a 是怎么推算来的
1≤a≤b≤c,证明log(a)(b)+log(b)(c)+log(c)(a)≤log(b)(a)+log(c)(b)+log(a)(c)
2log(b)x=log(a)x+log(c)x求证,c^2=(ac)^[log(a)b]
log(a)*log(b)=啥啊,忘记公式了啊 别告诉我等于log(b)*log(a)
化简log(1/a)b+log(a)b
log(a) (b ) 与log(b) (a)是什么关系
2^(log(a)(b))*8^(log(a)(b))
若| log a 1/4 |=log a 1/4 ,| log b a |=-log b a 则 a b满足什么条件0<a<1 b>1log旁边的a在下面
设a>b>1,log(a)b+log(b)a=10/3,则log(a)b-log(b)a=
已知a<b<1,log(a)b+log(b)a=10/3,求log(a)b-log(b)a的值括号为下标,
