0 −1

2 5

| e C= |

3 0

6 1

|, calcular:

a) A+B

b) A+C

c) B-C

d) A-B

e) A+B-C​

Answer 1

Resposta:

A = |2 1

−3 4|

B= |0 −1

2 5|

C= |3 0

6 1|

a)

A = |2 1

−3 4| A+B = | 2 0 |

| -1 9|

B= |0 −1

2 5|

b) A+C =

A = |2 1

−3 4| A+C =| 5 1 |

| 3 5 |

C= |3 0

6 1|

c) B-C =

B= |0 −1

2 5|

B-C = | -3 -1 |

| -4 4 |

C= |3 0

6 1|

d) A-B =

A = |2 1

−3 4|

A-B = | 2 2 |

| -5 -1 |

B= |0 −1

2 5|

e) A+B-C =

A = |2 1

−3 4|

B= |0 −1

2 5|

C= |3 0 A + B - C = | -1 0 |
