2log(m)y-log(m)x-log(m)z
log(3)4*log(4)8*log(8)M =log(2)16 M是多少
3、已知x,y,z都是大于1的正数,m>0,且log(x)m=24,log(y)m=40,log(xyz)m=12,则l
若log m 3
若log(2)4·log(4)8·log(8)m=log(4)16,求m的值
为什么-log(M/N)=log(N/M)
证明a(log(m)n)=n(log(m)a)
若log(2)3*log(3)4*...*log(31)32=M,则M的值为
1、以知x^2+y^2=1,x>0,y>0,且log以a为底的(x+1)=m,log以a为底的1/1-x=n,则log以
求证 log(a) (M·N)=log(a) M+log(a) N
已知log(2 )(3)=M,试用M表示 log(6)(9)=?
y=log(a)(x-3)+m恒过点(4,2),求m值.
log(2x)+log(3y)-log(2z) 怎么化简? log3(x^2-2x-6)=2 log(3x+6)=1+l
