answer attempt 1 out of 2
the given expression a polynomial.
submit answer

Explanation:

Step1: Recall polynomial definition

A polynomial is an expression of the form \(a_nx^n + a_{n - 1}x^{n - 1}+\dots+a_1x + a_0\), where \(n\) is a non - negative integer and \(a_i\) are constants. The exponents of the variable must be non - negative integers.

Step2: Analyze the given expression

The expression \(-\sqrt{b}\) can be rewritten as \(-b^{\frac{1}{2}}\). Here, the exponent of the variable \(b\) is \(\frac{1}{2}\), which is not a non - negative integer.

Answer:

The given expression is not a polynomial. So the answer for the blank is "is not".
