Question

If A and B are two square matrices which are skew symmetric then$(AB{)}^T$ equals to

• A. AB
• B. BA
• C. -AB
• D. -BA

Answer 1

The correct option is B BA

Required Expression,
$(AB{)}^T=B^T{A}^T$
= (-B) . (-A) (Since A and B are said to be skew symmetric)
= BA

$\therefore$ (b) is the right option.
