Question

Dada matriz C= (-3 1 2 -5) e o número real p=-2, calcule o produto p.c.

Answer 1

$C=\left[\begin{array}{cccc}-3&1&2&-5\end{array}\right]\\ \\p=-2\\ \\ \\p\cdot C=\left[\begin{array}{cccc}(-2)\cdot(-3)&(-2)\cdot1&(-2)\cdot2&(-2)\cdot(-5)\end{array}\right]\\ \\p\cdot C=\left[\begin{array}{cccc}6&-2&-4&10\end{array}\right]$
