In the matrix A = 2 5 19 -7 35 -2 5/2 12

Question

In the matrix A = \(\left[\begin{array}{cccc} 2 & 5 & 19 & -7 \\ 35 & -2 & \frac{5}{2} & 12 \\ \sqrt{3} & 1 & -5 & 17 \end{array}\right]\), write :

(i) The order of the matrix.

(ii) The number of elements. .

(iii) Write the elements a13, a21, a33, a24, a23.

Answer 1

(i) The order of the matrix = 3 x 4.
(ii) Hie number of elements = 3 x 4 = 12.
(iii) a13 = 19. a21 = 35, a33 = – 5, a24 = 12, a23 = \(\frac { 5 }{ 2 }\).
