Question

If m is a positive integer, then $(-m{)}^3$ is:

• A. Positive integer
• B. Negative Integer
• C. Zero
• D. None of these

Answer 1

The correct option is B Negative Integer

If m is a positive integer, then $m^3$ will also be a positive integer.
But $(-{)}^3$ means $(-)\times (-)\times (-)$, we know that $(-)\times (-)=(+)$ and, $(+)\times (-)=(-)$
Therefore $(-m{)}^3$ is a negative integer.
