" If "2^(x)=3^(y)=12^(2)," show that "(1)/(z)=(1)/(y)=+(2)/(x)

If 2^(x)=3^(y)=12^(z) show that (1)/(z)=(1)/(y)+(2)/(x)

If 2^(x)=3^(y)=12^(z) show that xy=z(x+2y)

If 2^x = 3^y =12^z show that 1/z= 1/y+2/x

If x + y + z = 12, x^(2) + Y^(2) + z^(2) = 96 and (1)/(x)+(1)/(y)+(1)/(z)= 36 . Then find the value x^(3) + y^(3)+z^(3).

If x + y + z = 12, x^(2) + Y^(2) + z^(2) = 96 and (1)/(x)+(1)/(y)+(1)/(z)= 36 . Then find the value x^(3) + y^(3)+z^(3).

If x+y+z=12 and x^(2)+y^(2)+z^(2)=96 and (1)/(x)+(1)/(y)+(1)/(z)=36 then the value x^(3)+y^(3)+z^(3) divisible by prime number is

If x + y + z = 12, x^(2) + Y^(2) + z^(2) = 96 and (1)/(x)+(1)/(x)+(1)/(z)= 36 . Then find the value x^(3) + y^(3)+z^(3).

(2-3x)/(x)+(2-3y)/(y)+(2-3z)/(z)=0 then (1)/(x)+(1)/(y)+(1)/(z)=

Show that the lines : (i) (x -5)/(7) = (y + 2)/(-5) = (z)/(1) " " and (x)/(1) = (y)/(2) = (z)/(3) (ii) (x - 3)/(2) = (y + 1)/(-3) = (z - 2)/(4) and (x + 2)/(2) = (y - 4)/(4) = (z + 5)/(2) are perpendicular to each other .

If x + y + z =xyz,show that (2x)/(1-x^2)+(2y)/(1-y^2)+(2z)/(1-z^2)=(2x)/(1-x^2).(2y)/(1-y^2).(2z)/(1-z^2)
