= 18 _____ 18

= _____

pls ans fast pls​

Answer 1

Answer:

=(2√3) × (3√3) - (2) × (-9)

=18 - (-18)

=36.

Answer 2

Given: A determinant $\left|\begin{array}{ccc}2\sqrt{3} &9\\2&3\sqrt{3} \end{array}\right|$

To find: value of determinant

Step-by-step explanation:

Step 1 of 1

$\left|\begin{array}{ccc}2\sqrt{3} &9\\2&3\sqrt{3} \end{array}\right|=a_{1} *a_{4} -a_{2} *a_{3}$

Substituting the values, we will get

$\left|\begin{array}{ccc}2\sqrt{3} &9\\2&3\sqrt{3} \end{array}\right|=2\sqrt{3} *3\sqrt{3} -9*2\\=6*3-18\\=18-18\\=0$

The value of the determinant is zero.
