Question

Observe as matrizes. A matriz W . Y é: *

Answer 1

Resposta:

$W*Y = \left[\begin{array}{ccc}20&8\\20&11\end{array}\right]$

Explicação passo a passo:

$W * Y= \left[\begin{array}{ccc}2&1&3\\4&2&1\\\end{array}\right] * \left[\begin{array}{ccc}1&3\\2&3\\4&1\end{array}\right]$

$W * Y = \left[\begin{array}{ccc}(2*3 )+(1*2)+(3*4) &(2*1)+(1*3)+(3*1)&\\(4*3)+(2*2)+(1*4)&(4*1)+(2*3)+(1*1)\end{array}\right]$

$W*Y = \left[\begin{array}{ccc}6+2+12&2+3+3\\12+4+4&4+6+1\end{array}\right]$

$W*Y = \left[\begin{array}{ccc}20&8\\20&11\end{array}\right]$
