If \[A = \begin{bmatrix}2 & - 1 & 3 \\ - 4 & 5 & 1\end{bmatrix}\text{ and B }= \begin{bmatrix}2 & 3 \\ 4 & - 2 \\ 1 & 5\end{bmatrix}\] then
पर्याय
only AB is defined
only BA is defined
AB and BA both are defined
AB and BA both are not defined
उत्तर
Given :
Order of A is 2 × 3 and order of B is 3 × 2.
Therefore, AB and BA both are defined.
Hence, the correct option is (c).
