Evaluate P + Q if possible.
2 answers:
Here we are given with <em>two matrices</em> as follows
And
We need to find<em> P+Q </em>. But , <em>matrix addition</em> is only possible iff the order of all <em>matrices</em> which are <em>being added</em> is <em>same</em> . Now , here order of <em>P</em> is <em>2 × 3</em> while that of <em>Q</em> is <em>3 × 3 </em>. So , <em>matrix</em> <em>addition</em> isn't <em>possible.</em>
<em>Hence , Option C) Not possible is correct</em>
