Ответ:
Both of your answers are correct.
Rules for polynomials:
1) If all of the variables
in a expression has exponents
that are positive, it is a
polynomial.
2) If the expression
has a negative exponent,
it's not a polynomial.
3) If the expression
has a fraction, it is
not a polynomial.
Ответ:
so you add 9+9+9+9+9+9+9+9+9
