2x2
nda
Question 2
Question
Se a matriz A é do tipo mxn, a matriz B é do tipo 3xp e a matriz AxB é do tipo 5x2, marque a alternativa com os valores de m, n e p
Answer
m=5, n=3 e p = 2
m=3, n=5 e p = 2
m=5, n=2 e p = 3
m=2, n=3 e p =5
Question 3
Question
Dadas as matrizes \(A = \left( \begin{array}{rr} 2 & 1 \\ 1 & 3 \end{array}\right)\) e \(B = \left( \begin{array}{rrr} 4 & 2 & 0 \\ 5 & 1 & 3 \end{array}\right)\), calcular \(A.B\)
Answer
\(AB = \left( \begin{array}{rrr} 13 & 5 & 3 \\ 5 & 1 & 3 \end{array}\right)\)
\(AB = \left( \begin{array}{rr} 13 & 5 \\ 5 & 1 \\ 3 & 3 \end{array}\right)\)
\(AB = \left( \begin{array}{rrr} 5 & 1 & 3 \\ 13 & 5 & 3 \end{array}\right)\)
\(AB = \left( \begin{array}{rr} 5 & 13 \\ 1 & 5 \\ 3 & 3 \end{array}\right)\)
Question 4
Question
Seja \(A = \left( \begin{array}{rr} 2 & -1 \\ 3 & 1 \end{array}\right)\) e \(B = \left( \begin{array}{rr} \frac{1}{5} & \frac{1}{5} \\ -\frac{3}{5} & \frac{2}{5} \end{array}\right)\). Então \(A.B = B.A\).
