Question

Please answer both question correctly​

Answer 1

Answer :-

• (ab - bc) + (bc - ca) + (ca - ab) = 0
• $\rm 4q \times 0 \longmapsto \bf 0$

Step-by-step-Explaination :-

3.) (ab - bc) + (bc - ca) + (ca - ab)

$\rm\implies \: \cancel{ab} \cancel{ - bc}+ \cancel{ bc} \cancel{ - ca} + \cancel{ca } \cancel{- ab}$

$\rm \implies \: \bf \: 0$

4. As we know that anything multiplied by 0 becomes 0 so, in this case it will also be zero.

$4.)\rm \: 4q \times 0 \longmapsto \bf 0$
