If `ax+by+cz = p`, then minimum value of `x^2 + y^2 + z^2` is

If 2x+3y+6z=14 then the minimum value of x^(2)+y^(2)+z^(2) is

3 natural numbers x, y, z are in G.P. & x, y^2, z are in A.P., then the minimum value of x +2y +z is equal to

three natural numbers X,y,z are in G.P.&x,y^(2),z are in A.P., then the minimum value of x+2y+z is equal to ?

If (x^(2))/(by+cz)=(y^(2))/(cz+ax)=(z^(2))/(ax+by)=1 , then value of (a)/(a+x) +(b)/(b+y) +(c )/(c+z) is
