2log(5)25＋3log(2)64＝?

2log(5)25＋3log(2)64＝? (log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8) 2log(5 ) 25+3log(2) 64-8log(2) 1 ( )内代表的是以什么为底 2log(5 ) 25+3log(2) 64-8log(2) 1 ( )内代表的是以什么为底 2^log(4)(3)加3^log(9)(1/4)加5^log(1/25)(2) log(2)(25)*log(3)(根号2)*log(5)(9)+_+ 请问为什么错? 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 log(4)25-2log(4)10+log(4)5*log(5)16 [log(5)8]*[log(32)5]+log(9)8/log(3)2 求等式log(2)3*log(3)4*log（4)5*log(5)6*log(6)7*log(7)m=log(3)9时m的值? 求值:(log(4)3+log(8)3)×(log(3)2+log(9)2)+log(2)(2^5)¼ log(2)5×log(5)81×log(3)4＋In√e.还有(log(2)3＋log(4)9)(log(3)4＋1／2log(3)2) log（x+5）=log（x）+log（2） log（8）+log（x）=log（24） 2log（x）=log(2x)+log(3) Log(2)1/25•log(3)1/8•log(5)1/9化简 还有已知log(18)9=a,log(18)5=b求log(36)45 值 已知log(2)^3＝a,log（3）^5=b,试用a,b表示log(15)^20 5/6log(2)3*3/2log(3)2
