यदि `D_(1)=|(y^(5)z^(6)(z^(3)-y^(3)),x^(4)z^(6)(x^(3)-z^(3)),x^(4)y^(5)(y^(3)-x^(3))),(y^(2)z^(3)(y^(6)-z^(6)),xz^(3)(z^(6)-x^(6)),xy^(2)(x^(6)-y^(6))),(y^(2)z^(3)(z^(3)-y^(3)),xz^(3)(x^(3)-z^(3)),xy^(2)(y^(3)-x^(3)))|` तथा `D_(2)=|(x,y^(2),z^(3)),(x^(4),y^(5),z^(6)),(x^(7),y^(8),z^(9))|` तो `D_(1)D_(2)` बराबर है
