Question

m=[-1 -4 -7]
5 2-1

n= [1 -1 -3 ]
4 2 0


considere as matrizes m e n dadas anteriormente e determine as matrizes pedidas:
A= m+n


B= n+m

C= m-n

D= n-m

​

Answer 1

Resposta:

A)

[-1 -4 -7] [1 -1 -3] [0 -5 -10]

[5 2 -1] + [4 2 0] = [9 4 -1 ]

B)

[1 -1 -3] [-1 -4 -7] [0 -5 -10]

[4 2 0] + [5 2 -1] = [9 4 -1]

C)

[-1 -4 -7] [1 -1 -3] [-2 -3 -4]

[5 2 -1] - [4 2 0] = [1 0 -1]

D)

[1 -1 -3] [-1 -4 -7] [2 3 4]

[4 2 0] - [5 2 -1] = [-1 0 1]
