Question

Construir a matriz a = (aij) 2x3 tal que aij = (i+j)2

Answer 1

Resposta:

$A=\left[\begin{array}{ccc}a_1_1&a_1_2&a_1_3\\a_2_1&a_2_2&a_2_3\\\end{array}\right] \\\\a_1_1=(1+1)^2=2^2=4\\a_1_2=(1+2)^2=3^2=9\\a_1_3=(1+3)^2=4^2=16\\a_2_1=(2+1)^2=3^2=9\\a_2_2=(2+2)^2=4^2=16\\a_2_3=(2+3)^2=5^2=25\\\\A=\left[\begin{array}{ccc}4&9&16\\9&16&25\\\end{array}\right]$
