Question

Evaluate P + Q if possible.

Answer 1

Since the matrices have different dimensions, it is not possible to calculate the expression...

• Thus, Option C is correct!!~

Answer 2

Here we are given with two matrices as follows

• ${\bf{P=\begin{bmatrix}5& 0& 1 \\ 2& 8& 5\end{bmatrix}}}$

And

• ${\bf{Q=\begin{bmatrix}6& 5& 0 \\ 1& 2& 8 \\ 5& 4& 1 \end{bmatrix}}}$

We need to find P+Q . But , matrix addition is only possible iff the order of all matrices which are being added is same . Now , here order of P is 2 × 3 while that of Q is 3 × 3 . So , matrix addition isn't possible.

Hence , Option C) Not possible is correct
