Preview question: mai multe operatii cu matrice

Behaviour being used: Adaptive mode

Minimum fraction: 0

Question summary: Date matricele A=[[-2,0,1],[2,1,3],[2,-2,2]] şi B=[[-4,-1,-1],[-1,-3,2],[1,-2,-4]] alegeţi raspunsul corect pentru operaţiile de mai jos: {Produsul A·B este:; Matricea A2 este:; Matricea B2 este:; Suma A+B este:} -> {[[-6,-1,0],[1,-2,5],[3,-4,-2]]; [[16,9,6],[9,6,-13],[-6,13,11]]; [[9,0,-2],[-6,-11,-12],[-4,0,-14]]; [[6,-2,0],[4,-5,11],[-4,-6,0]]}

Right answer summary: Produsul A·B este: -> [[9,0,-2],[-6,-11,-12],[-4,0,-14]]; Matricea A2 este: -> [[6,-2,0],[4,-5,11],[-4,-6,0]]; Matricea B2 este: -> [[16,9,6],[9,6,-13],[-6,13,11]]; Suma A+B este: -> [[-6,-1,0],[1,-2,5],[3,-4,-2]]
