Question

qual a matriz de a= aij 3x2 tal que aij =2i -j

Answer 1

2(1)-1 2(1)-2
2(2)-1 2(2)-2
2(3)-1 2(3)-2
1 0
3 2
5 4

Answer 2

(a11. a12) (1. 0)
(a21. a22) (3. 2)
(a31. a32) (5. 4)
aij=2i-j
a11=2.1-1=2-1=1
aij=2i-j
a21=2.2-1=4-1=3
aij=2i-j
a31=2.3-1=6-1=5
aij=2i-j
a12=2.1-2=2-2=0
aij=2i-j
a22=2.2-2=4-2=2
aij=2i-j
a32=2.3-2=6-2=4
