Question

What happens when we square $-{31}^2$?

• A. $961$
• B. $961i$
• C. $-961$
• D. $-961i$

Answer 1

The correct option is C $-961$

$-$$(31{)}^2$$=$$-$$(31\times 31)$ $=$ $-961$

Since the negative sign is not in the brackets. In other words, $-1\times 31\times 31=-961$

Hence, Option C is correct.
