log(3)2=a则log(2)9等于多少--------括号里是底数

log(2)9log(3)4等于 log(3)2=a则log(2)9等于多少--------括号里是底数 log(2)3=a,则log(6)4=（ 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? 公式a^log(a)N=N 的应用3^log(9)(lg2-1)^2 + 5^log(25)(lg0.5-2)^2 等于? log（2）25×log（3）4×log （5）9等于多少? log底数3[log底数4(log底数2y)]=0等于多少? （LOG(3,4)+LOG(3,8)）（LOG(2,3)+LOG(2,9)）等于几 看的懂吧 已知a=log₂3+log₂√3,b=log₂9-log₂√3,c=log₃2,则a,b,c的大小关系是? 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 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 log a 2/3 log a(2/3) 对数函数题 log a - log b = 3 log (c/2) 求 a = ______________ log(2)9×log(3)4 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(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 log以2为底的（log以3为底的（log以4为底的x))=log以3为底的（log以4为底的（log以2为底的y))=log以4为底（log以2为底的（log以3为底的z))=0,则x+y+z等于?这个我写的比较多,希望会的人不要觉的麻烦,.
