" If "2^(x+y)=2^(x-y)=sqrt(8)" then the value of "y" is "

If 2^(x + y ) = 2^(x - y ) = sqrt8 then the value of y is

If e^(x)=y+sqrt(1+y^(2) then the value of y is

If e^(x)=y+sqrt(1+y^(2) then the value of y is

Suppose that log_(10)(x-2)+log_(10)y=0 and sqrt(x)+sqrt(y-2)=sqrt(x+y) Then the value of (x+y) is

Suppose that, log_(10) (x-2) + log_(10) y=0 and sqrt(x)+sqrt(y-2)=sqrt(x+y) . Then the value of (x + y) , is

Suppose that, log_(10) (x-2) + log_(10) y=0 and sqrt(x)+sqrt(y-2)=sqrt(x+y) . Then the value of (x + y) , is

If (x-y,x+y)=(2,8), then the values of x and y are respectively.

If sqrt((x)/(y)) =(10)/(3) - sqrt((y)/(x)) and x-y=8 , then the value of xy is equal to
