Question

construir as matrizes determinadas pela fórmulas abaixo A2x2 tal que aij=4i-3j

Answer 1

Resposta:

$a_i_j=4i-3j$

$A_2_X_2=\left[\begin{array}{ccc}a_1_1&a_1_2\\a_2_1&a_2_2\\\end{array}\right] \\\\a_1_1=4.1-3.1=4-3=1\\\\a_1_2=4.1-3.2=4-6=-2\\\\a_2_1=4.2-3.1=8-3=5\\\\a_2_2=4.2-3.2=8-6=2\\\\A_2_X_2=\left[\begin{array}{ccc}1&-2\\5&2\\\end{array}\right]$
