Question

Degree of the polynomial ${}^{\prime }{2}^{\prime }$ is ___.

Answer 1

${}^{\prime }{2}^{\prime }$ can be written as $2x^0$.

This is a polynomial in one variable, and we know that degree of a polynomial in one variable is the greatest of the exponents of its various terms.

We have only one term here, which is $2$(or$2x^0$).

Hence the degree of the given polynomial is $0$.

Such a polynomial is called a constant polynomial.
