The given expression is a polynomial whose degree is $0$.

Work Step by Step

Using the rule $x^0=1$, the given expression is equivalent to: $=-\pi(1) \\=-\pi(x^0) \\=-\pi{x^0}$ The exponent of the variable is $0$, which is a nonnegative integer. Thus, the given expression is a monomial and is consequently a polynomial. The degree of a nonzero polynomial in one variable is equal to the exponent of the variable. Thus, the degree of the polynomial is 0.
