Question

Determine a matriz A= aij) 2x3 tal que aij = i2 + j

Answer 1

Resposta:

Explicação passo a passo:

$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_i_j=(i^2+j)\\\\a_1_1=(1^2+1)=1+1=2\\\\a_1_2=(1^2+2)=(1+2)=3\\\\a_1_3=(1^2+3)=(1+3)=4\\\\a_2_1=(2^2+1)=(4+1)=5\\\\a_2_2=(2^2+2)=(4+2)=6\\\\a_2_3=(2^2+3)=(4+3)=7$$A=\left[\begin{array}{ccc}2&3&4\\5&6&7\\\end{array}\right]$
