Let x,y,z be positive real numbers such that`log_(2x)z=3, log_(5y)z=6` and `log_(xy)z=2/3` then the value of z is

The x,y,z are positive real numbers such that log_(2x)z=3,log_(5y)z=6, and log_(xy)z=(2)/(3), then the value of ((1)/(2z)) is .........

The x , y , z are positive real numbers such that (log)_(2x)z=3,(log)_(5y)z=6,a n d(log)_(x y)z=2/3, then the value of (1/(2z)) is ............

The x , y , z are positive real numbers such that (log)_(2x)z=3,(log)_(5y)z=6,a n d(log)_(x y)z=2/3, then the value of (1/(2z)) is ............

The x , y , z are positive real numbers such that (log)_(2x)z=3,(log)_(5y)z=6,a n d(log)_(x y)z=2/3, then the value of (1/(2z)) is ............

The x , y , z are positive real numbers such that (log)_(2x)z=3,(log)_(5y)z=6,a n d(log)_(x y)z=2/3, then the value of (1/(2z)) is ............

Let x,y and z be positive real numbers such that x^(log_(2)7)=8,y^(log_(3)5)=81 and z^(log_(5)216)=(5)^((1)/(3)) The value of (x(log_(2)7)^(2))+(y^(log_(3)5)^^2)+z^((log_(5)16)^(2)), is

If log_(x)(z)=4,log_(10y)(z)=2 and log(xy)(z)=(4)/(7), then z^(-2) is equal to :

Let W,X,Y and Z be positive real number such that log(W.Z)+log(W.Y)=, log(Y.Z)+log(Y.X)+log(X.Z)=4 log(W.Z) + log(W.Y)=2, log(Y.Z)+log(Y.X)=3, log(X.Z)=4 . The value of the product (WXYZ) equals (base of the log is 10)
