The real and y satisfy `log_8 x + log_4 y^2=5` and `log_8 y +log_4 x^2=7`, find xy.

If log_2 x+log_4 y+log_4 z=2 then x^2yz=

If x and y satisfy the following system of equations, log x – log y = -2 , log x + 2 log y=1 then the value of xy is

if log_(9)x+log_(4)y=(7)/(2) and log_(9)x-log_(8)y=-(3)/(2) then x+y is

If log_y x +log_x y=7, then the value of (log_y x)^2+(log_x y)^2, is

If 2"log"_(8) a =x, "log"_(2) 2a = y " and " y-x =4, then x =

If 2"log"_(8) a =x, "log"_(2) 2a = y " and " y-x =4, then x =

If log_(2)x+log_(x)2=(10)/(3)=log_(2)y+log_(y)2 and x!=y find x+y

Solve for x, y , z . log_2 x + log_4 y + log_4 z =2 log_3 y + log_9 z + log_9 x =2 log_4 z + log_16 x + log_16 y =2
