Question

If $a{x}^n$ is a zero degree polynomial in x, what can be said about a?

• A. Both a and n are zero
• B. (a+n) is zero.
• C. n is non zero
• D. a is non zero

Answer 1

The correct option is D

a is non zero

A zero degree polynomial is essentially a constant, i.e. any non-zero real number. So, n has to be zero, and a should not be zero.
