Question

If A = $$\begin{bmatrix*}[r] -1 & 2 \end{bmatrix*} 	ext{ and } B = \begin{bmatrix*}[r] 1 & -2 \ 0 & 3 \end{bmatrix*}$$. Which of the following operations is possible ?

Accepted Answer

Order of A : 1 × 2 and order of B : 2 × 2 Since, no. of columns in A is same as the no. of rows in B. ∴ AB is possible. Hence, Option 3 is the correct option.
