(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
=(lg125/lg2+lg25/lg2+lg5/lg8)(lg2/lg125+lg4/lg25+lg8/lg5)
=(3lg5/lg2+2lg5/lg2+lg5/3lg2)(lg2/3lg5+2lg2/2lg5+3lg2/lg5)
=(3+2+1/3)*(lg5/lg2)*(1/3+1+3)*(lg2/lg5)
=16/3*13/3
=208/9
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
=[3log2 5+2log2 5 +(log2 5)3]*[(log5 2)/3+log5 2+3log5 2]
=[(16log2 5)/3]*[(13log5 2)/3]
=208/9

(log下2上125+log下4上25+log下8上5)(log下5上2+log下25上4+log下25上8)怎么算
2log(5)25＋3log(2)64＝?
log(10)(25/9)减log(10)(7/4)减log(10)(1/9)加1/2log(10)(49)
2^log(4)(3)加3^log(9)(1/4)加5^log(1/25)(2)
log二25×log三2√2×log五9=?
log(2)(25)*log(3)(根号2)*log(5)(9)+_+ 请问为什么错?
求log₂25×log₃2√2×log(5)9的结果,
log（2）25×log（3）4×log （5）9等于多少?
log(2)(25)×log(3)(1/16)×log(5)(1/9)=?
log(2)1/25乘以log(3)1/8乘以log(5)1/9
2log(m)y-log(m)x-log(m)z
log(2)9log(3)4等于
log(2)9×log(3)4
4^[log(2)3+log(4)8]
log(27)32 × log(64)27+log(9)2 × log(4)根号27=?log(27)32 × log(64)27+log(9)2 × log(4)根号27=?
log平方2是什么
