Question

Calcule o determinante da seguinte matriz:

Answer 1

Explicação passo-a-passo:

$\sf det~(D)=\dfrac{1}{2}\cdot\sqrt{2}-1\cdot\sqrt{8}$

$\sf det~(D)=\dfrac{\sqrt{2}}{2}-\sqrt{8}$

$\sf det~(D)=\dfrac{\sqrt{2}}{2}-2\sqrt{2}$

$\sf det~(D)=\dfrac{\sqrt{2}-4\sqrt{2}}{2}$

$\sf det~(D)=\dfrac{-3\sqrt{2}}{2}$
