The answer is yes, the rational points on your surface lie dense in the real topology Let's consider the projective surface S over Q given by X 3 Y 3 Z 3 − 3 X Y Z − W 3 = 0 It contains your surface as an open subset, so to answer your question we might as well show that S ( Q) is dense in S ( R) Observe that S has a singularTrả lời (1) • V T =(xyz)3−x3−y3−z3 V T = ( x y z) 3 − x 3 − y 3 − z 3 = (xy)33z(xy)2 3(xy)z2z3−x3−y3−z3 = ( x y) 3 3 z ( x y) 2 3 ( x y) z 2 z 3 − x 3 − y 3 − z 3 = x33x2y3xy2y33z(xy)2 3xz2 3yz2−x3 −y3 = x 3 3 x 2 y 3 x y 2 y 3 3 z ( x y) 2 3 x z 2 3 y z 2 − x 3 − y 3Equations Tiger Algebra gives you not only the answers, but also the complete step by step method for solving your equations 3*3x*y*4z*x*y*z so that you understand better
