已知log(a)ab=1/p,则log(ab)a/b=____.已知log(a)ab=1/p,则log(ab)a/b=____.已知log(a)ab=1/p,则log(ab)a/b=____.log(
已知 log (a) ab=1/p ,则 log (ab) a/b=__ __.
已知 log (a) ab=1/p ,则 log (ab) a/b=__ __.
已知 log (a) ab=1/p ,则 log (ab) a/b=__ __.
log (a) ab=1/p ,Log(a)a+Log(a)b=1/p,1+Log(a)b=1/p
Log(a)b=(1-p)/p
log (ab) a/b=(换底)
=[Log(a)a/b]/Log(a)(ab)
=[Log(a)a/b]/(1/p)
=p[Log(a)a/b]
=p[LOg(a)a-LOg(a)b]
=p[1-(1-p)/p]
=p-(1-p)
=2p-1
已知 log (a) ab=1/p ,则 log (ab) a/b=__ __.
关于数学对数的换底公式推论的问题已知 log(2)(3) = a,log(3(7)=b,用a,b表示log(42)(56)因为log(2)(3)=a,则1/a=log(3)(2),又∵log(3)(7)=b,∴log(42)(56)=log(3)(56)/log(3)(42)=log(3)(7)+3·log(3)(2)/log(3)(7)+log(3)(2)+1=ab+3/ab+b+1

已知P((AB)反)=1/16,P(AB)=P(A)P(B),P((A反)B)=P(A(B反)),则P(A)=
log a c+log b c=0(c≠1),则ab+c-abc=?
log a c+log b c=0(c≠1),则ab+c-abc=?
已知a+b=5,且a>0,b>0,则log(1/2)(ab^2)有( )A,最小值-2B,最大值-2C,最小值log(1/2) (500/27)D,最大值log(1/2)(1000/27)
高一数学对数指数函数运算1若3^x=4^y=36,则2/x+1/y=?2方程lg(4^x + 2)=lg2^x+lg3的解是3已知log a为底数的ab次方=1/p,则log以ab为底数的a/b次方=?
已知P(B/A)=1/2,P(A)=3/5,则p(AB)
已知log(3)2=a log(5)2=b用ab表示log(30)90
已知log(a)x=1,log(b)x=2,log(c)x=4,则log(abc)x=?
已知log(14)7=a log(14)5=b 用ab表示log(35)70=log(3)4*log(4)8*log(8)m=log(4)2 求m
已知a>0且a≠1,P=loga(a²-a+1),Q=(a³-a+1),则P,Q的大小关系是Q=log(a³-a+1), 过程。
log a b=log b a,则:ab=?a不等于b
已知ab=M(a>0,b>0,M不等于1),且log(M)(b)=x,ze log(M)(a)等于_____
已知ab=c(a>0,b>0且c≠1),log(c)b=x,试用x表示log(c)a那个c是底数.
1 (lg5)^2+lg50*lg22 若A大于1,b大于1,P=log↓b(log↓b A)/log↓b A 则A^p=?
log(a)(b)=log(b)(a)(a≠1,b≠1,c≠1),则ab=(log(x)(y))^2+(log(y)(x))^2=1,则y可用x表示为前面那个括号是底数
