Question

Construa a matriz A=(aij) 3x3, tal que aij = i+3j.

Answer 1

a¹¹ a¹² a¹³ a¹¹ = 1+3.1= 4 a¹²= 1+3.2=7 a¹³= 1+3.3=10

a²¹ a²² a²³ a²¹= 2+3.1=5 a²²= 2+3.2=8 a²³= 2+3.3=11

a³¹ a³² a³³ a³¹= 3+3.1=6 a³²= 3+3.2= 9 a³³= 3+3.3=12

matriz pronta:

$\left[\begin{array}{ccc}4&7&10\\5&8&11\\6&9&12\end{array}\right]$
