Answer:
8) Number of terms : Monomial
Degree : Constant polynomial
9) Not a polynomial
Step-by-step explanation:
8) Recall that a polynomial with one term is a monomial
A polynomial with a degree of zero is a constant polynomial
Therefore 1 is a monomial, when we classify by number of terms and it is a constant polynomial when we classify by degree since the degree is zero.
9) Note that a polynomial has positive integral indices, therefore
is not a polynomial.
The reason is that,
but
is not an integer.
