Answer 1

hy mate here is your anshwer=>>

=4 3::2 7

=12/27✔

is your anshwer

Answer 2

The value of this determinant is found by finding the difference between the diagonally down product and the diagonally up product.

D = $\left[\begin{array}{cc}m_1&m_3\\m_2&m_4\end{array}\right] = m_1*m_4 - m_2 *m_3$

here, D = $\left[\begin{array}{cc}4&3\\2&7\end{array}\right]$

D = 7 * 4 - ( 3 ) * ( 2 )

D = 28 - 6

D = 22
