<prompt> Tafuta matrix mathbfM ambayo huongeza mara tatu safu mlalo ya pili ya matrix. Kwa maneno mengine,mathbfM anzapmatrix a b c d endpmatrix anzapmatrix a b 3c 3d endpmatrix.Kama hakuna vile matrix mathbfM ipo, kisha ingiza sifuri matrix.  <response>: Acha mathbfM anzepmatrix p q r s endpmatrix. KishamathbfM anzapmatrix a b c d mwishopmatrix anzapmatrix p q r s mwishopmatrix anzapmatrix a b c d endpmatrix anzapmatrix pa qc pb qd ra sc rb sd endpmatrix.Tunataka hii iwe sawa na anzapmatrix a b 3c 3d endpmatrix. Tunaweza kufanikisha hili kwa kuchukua p 1, q 0, r 0, na s 3, hivyo mathbfM anzapmatrix 1 0 0 3 endpmatrix.
