[" The pole of "lx+my+n=0],[" W.r.t the circle "x^(2)+y^(2)=x^(2)],[" is "]

If the pole of a line w.r.t to the circle x^(2)+y^(2)=a^(2) lies on the circle x^(2)+y^(2)=a^(4) then the line touches the circle

If the pole of a line w.r.t to the circle x^(2)+y^(2)=a^(2) lies on the circle x^(2)+y^(2)=a^(4) then find the equation of the circle touched by the line.
