Answer:

It's not a polynomial.

Step-by-step explanation:

In this case, we are given with the number " 2√-7 ".

In " 2√-7 ", the number " 2 " is a whole number and also a natural number but "√-7 " is not a whole number or a natural number. According to polynomials, any number which is a whole number, natural number or an integer can be a polynomial. But according to " 2√-7 ", it's just partially a polynomial and thus it's not a polynomial.
