| c d| = | 2² - 1 1 |

Answer 1

TEMA: DETERMINANTES

$\left|\begin{array}{c}A B \\C D\end{array}\right|=\left|\begin{array}{cc}6 \% & 33^{3} \\2^{2} & -11\end{array}\right|$

$6 \% \: \times \: ( - 11) \: - \: {33}^{3} \: \times \: {2}^{2}$

$\frac{6}{100} \: \times \: ( - 11) \: - \: {33}^{3} \: \times \: 4$

$- \frac{3}{50} \: \times \: 11 \: - \: 4 \: \times \: {33}^{3}$

$- \frac{33}{50} \: - \: 4 \: \times \: 35937$

$- \frac{33}{50} \: - \: 143748$

$\boxed{ \bold{ - \frac{ 7187433}{50} }}$
