Answer:
9z to the negative two power is a polynomial.
Step-by-step explanation:
It is determined as a monomial because it only has one term. And the degree would be -2 because the degree of any polynomial when you put it in standard form is the exponent of the leading term. The leading term is the first term that is in the expression or polynomial. I hope this makes sense. If it doesn't, just comment and I can help you more. :)
