Question

If the exponent of a negative integer is even then the result is a ____ integer.

• A. positive
• B. negative
• C. $0$
• D. none of the above

Answer 1

The correct option is A positive

If the exponent of a negative integer is even, then the result is a positive integer.

For eg.

$(-2{)}^2=(-2)\times (-2)=2\times (-1)\times 2\times (-1)=4\times 1=4$

$(-1{)}^4=(-1)\times (-1)\times (-1)\times (-1)=1\times 1=1$

Hence, option A is correct.
