已知x>y>0,log3(x-y/2)^2=log3(xy),则log3(根号x/y-根号2) 求全过程紧急求啊
已知x>y>0,log3(x-y/2)^2=log3(xy),则log3(根号x/y-根号2) 求全过程
紧急求啊
已知x>y>0,log3(x-y/2)^2=log3(xy),则log3(根号x/y-根号2) 求全过程紧急求啊
由已知得根号x/y=(根号3+1)/2小于根号2,因此此题有误
已知x>y>0,log3(x-y/2)^2=log3(xy),则log3(根号x/y-根号2)
已知x>y>0,log3(x-y/2)^2=log3(xy),则log3(根号x/y-根号2)多少
已知x>y>0,log3(x-y/2)^2=log3(xy),则log3(根号x/y-根号2) 求全过程紧急求啊
已知2log3[(x—y) / 2]=log3(xy),则x / y=_________.
